Creating an endpoint for keeping the session alive IIS 7.5 - asp.net-mvc

At my work we have a standard timeout script that waits for 15 mins and prompts a user asking if they want to continue the session. Is there anyway within IIS to create a dummy endpoint that the script can be changed to call to refresh the session. For all our applications we use the same script so I want it to be the same end point for each application. I was leaning toward creating an HTTP handler to do this, however I wasn't sure if this was enough. I'm looking to emulate the approach taken here.
Keeping ASP.NET Session Open / Alive
public class SessionKeepAliveHttpHandler : IHttpHandler, IRequiresSessionState
{
public bool IsReusable
{
get { return true; }
}
public void ProcessRequest(HttpContext context)
{
//Give it some long name it's no one is likely to have used
context.Session["Global_Session_KeepAlive"] = System.DateTime.Now;
}
and registering the handler like this
<httpHandlers>
<add verb="POST" path="keep-alive.html" validate="false" type="SessionKeepAliveHttpHandler"/>
</httpHandlers>
I'm also not 100% sure about where to register the handler, reading online here it looks like I'd put it in the Machine.config. However I wasn't sure as I don't have direct access to the ISS server.
By default our session timeout script is setup to make a post request to just "keep-alive.html"

Async Function Fails when called as part of a Constructor

I'm rather new to Blazor, but I am currently trying to get access to some classes from within a class library that I've created and deployed as a Nuget package. As background, the Nuget package is an Api library, which allows me to talk to a webservice (I don't know if this is relevant or not). However, every time I go to the page where I'm testing, the page never loads and instead I left looking at the browser loading circle until I navigate away or close the application. During my testing here, it seems like it's the #inject call of my interface into the Blazor component which is causing the issue as when I remove it and try to load the page normally, the page does so.
So to demonstrate what I have setup, here is where I've added the Singletons to the DI:
builder.Services.AddSingleton<IApiConfigHelper, ApiConfigHelper>();
builder.Services.AddSingleton<IApiHelper, ApiHelper>();
builder.Services.AddSingleton<ISystemEndpoint, SystemEndpoint>();
Then on the blazor page, I have the following declarations at the top of my page:
#using Library.Endpoints
#using Library.Models
#page "/"
#inject ISystemEndpoint _systemEndpoint
Now I am leaning towards is this something to do with the Nuget package and using it with DI. I have tested the library away from this project (In a console application) and can confirm it's working as it should.
I have also created a local class library as a test to, to see if I could inject a data access class into the page and I can confirm that this works without an issue, which suggests to me that DI is working, just not with my Nuget package.
I did have a look into CORS, given that the Nuget package is accessing an external domain, and setup the following simple CORS policy in the app:
builder.Services.AddCors(policy =>
{
policy.AddPolicy("OpenCorsPolicy", opt =>
opt.AllowAnyOrigin()
.AllowAnyHeader()
.AllowAnyMethod());
});
Which is added to the app after the AddRouting call like so:
app.UseCors("OpenCorsPolicy");
However again, this wasn't the solution so if anyone is able to point me in the right direction with where I may be going wrong with this or offer any advice, I would be most grateful.
EDIT 1 - Provides details #mason queried
Regarding SystemEndpoint, the constructor is being injected with 2 things, as below:
public SystemEndpoint(IApiHelper apiHelper, IOptions<UriConfigModel> uriOptions)
{
_apiHelper = apiHelper;
_uriOptions = uriOptions.Value;
}
My Nuget Library is dependant on the following:
Azure.Identity
Azure.Security.KeyVault.Secrets
Microsoft.AspNet.WebApi.Client
Microsoft.Extensisons.Options.ConfigurationExtensions
EDIT 2 - Doing some further testing with this I have added a simple Endpoint class to my Nuget library, which returns a string with a basic message, as well as returning the values of the 2 UriConfig properties as below. I added this test to 1) sanity check that my DI was working correctly, and 2) check the values that are being assigned from appsettings to my UriConfig Object.
public class TestEndpoint : ITestEndpoint
{
private readonly IOptions<UriConfigModel> _uriConfig;
public TestEndpoint(IOptions<UriConfigModel> uriConfig)
{
_uriConfig = uriConfig;
}
public string TestMethod()
{
return $"You have successfully called the test method\n\n{_uriConfig.Value.Release} / {_uriConfig.Value.Version}";
}
}
However when adding in the dependency of IApiHelper into the Ctor, the method then breaks and fails to load the page. Looking into ApiHeloer, the Ctor has a dependency being injected into it of IApiConfigHelper. Looking at the implementation, the Ctor of ApiConfigHelper is setting up the values and parameters of the HttpClient that should make the REST calls to the external Api.
Now I believe what is breaking the code at this point is a call I'm making to Azure Key Vault, via REST, to pull out the secret values to connect to the Api. The call to KeyVault is being orchestrated via the following method, making use of the Azure.Security.KeyVault.Secrets Nuget Package, however I assume that at the heart of it, it's making a REST call to Azure on my behalf:
private async Task<KeyVaultSecret> GetKeyVaultValue(string secretName = "")
{
try
{
if (_secretClient is not null)
{
var result = await _secretClient.GetSecretAsync(secretName);
return result.Value;
}
}
catch (ArgumentException ae)
{
Console.WriteLine(ae.Message);
}
catch (Azure.RequestFailedException rfe)
{
Console.WriteLine(rfe.Message);
}
return new(secretName, "");
}
So that's where I stand with this at the moment. I still believe it could be down to CORS, as it seems to be falling over when making a call to an external service / domain, but I still can say 100%. As a closing thought, could it be something as simple as when I call call the above method, it's not being awaited????
So after persisting with this it seems like the reason it was failing was down to "awaiting" the call to Azure KeyVault, which was happening indirectly via the constructor of ApiConfigHelper. The resulting method for getting KeyVault value is now:
private KeyVaultSecret GetKeyVaultValue(string secretName = "")
{
try
{
if (_secretClient is not null)
{
var result = _secretClient.GetSecret(secretName);
if (result is not null)
{
return result.Value;
}
}
}
catch (ArgumentException ae)
{
Console.WriteLine(ae.Message);
}
catch (Azure.RequestFailedException rfe)
{
Console.WriteLine(rfe.Message);
}
return new(secretName, "");
}
I am now able to successfully make calls to my library and return values from the Api it interacts with.
I can also confirm that this IS NOT a CORS issue. Once I saw that removing the await was working, I then removed the CORS policy declarations from the service and the app in my Blazor's start-up code and everything continued to work without an issue.
As a final note, I must stress that this is only seems an issue when using the library with Blazor (possibly webApi projects) as I am able to use the library, awaiting the Azure call just fine in a console application.

Azure RoleEnvironment.Changing event not being called in ASP.NET MVC 5

I am trying to use the Azure Runtime Reconfiguration Pattern to allow me to change a appSetting in the normal Web.config file via PowerShell (later by Microsoft Azure Web Sites Management Library).
My problem is that the RoleEnvironment.Changing event is not being called in my MVC app, so the web app is being restarted. I have placed event set up code in the MVC Application_Start as described in the Azure article, i.e.
protected void Application_Start()
{
RoleEnvironment.Changing += RoleEnvironment_Changing;
RoleEnvironment.Changed += RoleEnvironment_Changed;
//normal MVC code etc...
AreaRegistration.RegisterAllAreas();
}
The event handlers are a straight copy of the handled from the Azure article and look like this:
private const string CustomSettingName = "TestConfig";
public static string TestConfigValue;
private static void RoleEnvironment_Changing(object sender,
RoleEnvironmentChangingEventArgs e)
{
RoleLogs.Add("RoleEnvironment_Changing: started");
var changedSettings = e.Changes.OfType<RoleEnvironmentConfigurationSettingChange>()
.Select(c => c.ConfigurationSettingName).ToList();
Trace.TraceInformation("Changing notification. Settings being changed: "
+ string.Join(", ", changedSettings));
if (changedSettings
.Any(settingName => !string.Equals(settingName, CustomSettingName,
StringComparison.Ordinal)))
{
Console.WriteLine("Cancelling dynamic configuration change (restarting).");
RoleLogs.Add("RoleEnvironment_Changing: restarting!");
// Setting this to true will restart the role gracefully. If Cancel is not
// set to true, and the change is not handled by the application, the
// application will not use the new value until it is restarted (either
// manually or for some other reason).
e.Cancel = true;
}
else
{
RoleLogs.Add("RoleEnvironment_Changing: change is OK. Not restarting");
Console.WriteLine("Handling configuration change without restarting. ");
}
}
private static void RoleEnvironment_Changed(object sender,
RoleEnvironmentChangedEventArgs e)
{
RoleLogs.Add("RoleEnvironment_ChangED: Starting");
Console.WriteLine("Updating instance with new configuration settings.");
foreach (var settingChange in
e.Changes.OfType<RoleEnvironmentConfigurationSettingChange>())
{
if (string.Equals(settingChange.ConfigurationSettingName,
CustomSettingName,
StringComparison.Ordinal))
{
// Execute a function to update the configuration of the component.
RoleLogs.Add("RoleEnvironment_ChangED: TestConfig has changed");
Console.WriteLine("TestConfig has changed.");
TestConfigValue = RoleEnvironment.GetConfigurationSettingValue(CustomSettingName);
}
}
}
I have added logs which prove that my RoleEnvironment_Changing and RoleEnvironment_Changed are not being called in the MVC WebApp which means the WebApp is restarted when I change an appSetting via PowerShell. This also means the RoleEnvironment.Changing event never gets to the WebJob.
I am using Azure SDK 2.7.0
Any ideas?
UPDATE
#richag gave me an answer, which made me realise that my problem is because I am using a App Service rather than a Cloud Service. This SO answer and plus this video (see at 5:00mins) talks about the difference (Note: the video is old so the name of the web app is different, but the concept is the same).
I don't really want to change this late in the development, and I have worked round the problem another way. Maybe on the next project and will look at Cloud Services as I can see some positives, like better control of my WebJobs configuration.
From the runtime reconfiguration pattern: "Microsoft Azure Cloud Services roles detect and expose two events that are raised when the hosting environment detects a change to the ServiceConfiguration.cscfg files" These events are not fired if you make changes to app.config/web.config files. Only when the cloud service configuration is changed, i.e. if you upload a new configuration file through the azure portal's configure tab or change a setting directly on the azure portal.
According to the debugger, none of the following events are fired when I update the Azure Portal to change an AppSetting for an ASP.NET WebAPI app:
RoleEnvironment.Changing
RoleEnvironment.Changed
RoleEnvironment.StatusCheck
RoleEnvironment.SimultaneousChanging
RoleEnvironment.SimultaneousChanged
RoleEnvironment.Stopping
Do others have different experience?

Why doesn't my action method time out?

I have the following controllers:
[TimeoutFilter]
public abstract class BaseController: Controller
{
}
public class IntegrationTestController : BaseController
{
[HttpGet]
public ActionResult TimeoutSeconds()
{
return Content(HttpContext.Server.ScriptTimeout.ToString(CultureInfo.InvariantCulture));
}
[HttpGet]
public ActionResult ForceTimeout()
{
var timeoutWindow = TimeoutFilter.TimeoutSeconds;
Thread.Sleep((timeoutWindow + 5) * 1000);
return Content("This should never get returned, mwahahaaa!");
}
}
For my test scenario I use a config setting of 5 seconds in the TimeoutFilter, and I know this is working because when my test calls TimeoutSeconds, I get the correct value of 5, but when the test calls ForceTimeout, I get an HTTP response of 200 and my 'never returned' text.
And the filter:
public class TimeoutFilter : ActionFilterAttribute
{
internal const string TimeoutSecondsSettingsKey = "MvcActionTimeoutSeconds";
internal static int TimeoutSeconds;
public TimeoutFilter()
{
TimeoutSeconds = int.Parse(ConfigurationManager.AppSettings[TimeoutSecondsSettingsKey]);
}
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
filterContext.Controller.ControllerContext.HttpContext.Server.ScriptTimeout = TimeoutSeconds;
base.OnActionExecuting(filterContext);
}
}
I could not get this to work by setting the ScriptTimeout property either, even when setting the debug="false" in the web.config as suggested by user Erik Funkenbusch:
<configuration>
<system.web>
<compilation debug="false" targetFramework="4.5"/>
...
It continued to return the text "This should never get returned" rather than timing out during the Thread.Sleep.
It is also worth noting that I also extended the Thread.Sleep to well beyond the Server.ScriptTimeout default of 110 seconds but it still eventually returned the same text rather than timing out.
I then instead tried to set executionTimeout in the web.config:
<configuration>
<system.web>
<httpRuntime targetFramework="4.5" executionTimeout="5"/>
...
If you were to now add a breakpoint to the TimeoutFilter you will observe that the ScriptTimeout value has been set to the executionTimeout value from web.config. Alas, this still did not work for me (regardless of whether debug="false").
I then came across this link about ScriptTimeout and executionTimeout not working with a similar setup to what you describe. The first reply in the post describes using the debug="false" and also mentions that the timeout will have a delay of 5 to 15 seconds. I still had no luck even when using a large Thread.Sleep value. The second reply in this article suggests that the executionTimeout config setting is a replacement of the ScriptTimeout property (which is apparently a COM interface used in classic ASP). This reply suggests that is not possible to set a specific timeout without using your own time-out logic.
Further, I then came across the following (more recent) link where the first reply suggests that the timeout is switched off in MVC. A further reply suggests that this is because an MVCHandler (which selects the controller that will handle the HTTPRequest) is an IHttpAsyncHandler and as it may therefore be executing another request (which is the point of using an async request) it therefore internally switches the time-out state off (this is what I gather from reading this link). It must work with straight asp.net though as using ScriptTimeout seems to be the accepted way in this answer.
The link suggests that adding the following line will allow it to work (but not in a medium trust application):
System.Web.HttpContext.Current.GetType().GetField("_timeoutState", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(System.Web.HttpContext.Current, 1);
Therefore, changing the TimeoutFilter OnActionExecuting() to:
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
System.Web.HttpContext.Current.GetType().GetField("_timeoutState", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(System.Web.HttpContext.Current, 1);
base.OnActionExecuting(filterContext);
}
and setting the web.config:
<configuration>
<system.web>
<compilation debug="false" targetFramework="4.5"/>
<httpRuntime targetFramework="4.5" executionTimeout="5"/>
...
allows the time-out to work but has the slight 5 second delay that is mentioned in the first post.
Note: Using this method does not allow you to set the ScriptTimeout property in the filter. Trying to set ScriptTimeout and override the value set in web.config does not appear to work.
Are you using a debug build?
From the ScriptTimeout documentation:
http://msdn.microsoft.com/en-us/library/system.web.httpserverutility.scripttimeout(v=vs.110).aspx
If you set the debug attribute of the compilation element to true in the Web.config file, the value of ScriptTimeout will be ignored.
Also, since this value is the same as that set on the httpRuntime element, I really don't understand the point of this, since you can just configure that setting in in your web.config instead.
Edit:
Dangerous has done a good job of finding out the details, and indeed, ScriptTimeout is unsupported in asynchronous pipelines (which MVC has been since at least MVC4 I think, as well as WebApi.. even if not using async methods)
The "workaround" as suggested by this connect report:
https://connect.microsoft.com/VisualStudio/feedback/details/781171/asp-net-mvc-executiontimeout-does-not-work
Use the [AsyncTimeout] attribute, and take a cancelation token as a parameter, then call CanclationToken.ThrowIfCancelationRequested periodically, or use the cancellation token in an async method.
Here's an example:
[AsyncTimeout(5000)]
public async Task<ContentResult> Index(CancellationToken ct)
{
await Task.Delay(10 * 1000, ct);
return Content("This should never get returned, mwahahaaa!");
}
This throws an OperationCanceled exception with a YSOD after 5 seconds. The bonus for this is that it works even in Debug mode ;)

The anti-forgery token could not be decrypted

I have a form:
#using (Html.BeginForm(new { ReturnUrl = ViewBag.ReturnUrl })) {
#Html.AntiForgeryToken()
#Html.ValidationSummary()...
and action:
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginModel model, string returnUrl, string City)
{
}
occasionally (once a week), I get the error:
The anti-forgery token could not be decrypted. If this application is
hosted by a Web Farm or cluster, ensure that all machines are running
the same version of ASP.NET Web Pages and that the configuration
specifies explicit encryption and validation keys. AutoGenerate cannot
be used in a cluster.
i try add to webconfig:
<machineKey validationKey="AutoGenerate,IsolateApps"
decryptionKey="AutoGenerate,IsolateApps" />
but the error still appears occasionally
I noticed this error occurs, for example when a person came from one computer and then trying another computer
Or sometimes an auto value set with incorrect data type like bool to integer to the form field by any jQuery code please also check it.
I just received this error as well and, in my case, it was caused by the anti-forgery token being applied twice in the same form. The second instance was coming from a partial view so wasn't immediately obvious.
validationKey="AutoGenerate"
This tells ASP.NET to generate a new encryption key for use in encrypting things like authentication tickets and antiforgery tokens every time the application starts up. If you received a request that used a different key (prior to a restart for instance) to encrypt items of the request (e.g. authenication cookies) that this exception can occur.
If you move away from "AutoGenerate" and specify it (the encryption key) specifically, requests that depend on that key to be decrypted correctly and validation will work from app restart to restart. For example:
<machineKey
validationKey="21F090935F6E49C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7
AD972A119482D15A4127461DB1DC347C1A63AE5F1CCFAACFF1B72A7F0A281B"
decryptionKey="ABAA84D7EC4BB56D75D217CECFFB9628809BDB8BF91CFCD64568A145BE59719F"
validation="SHA1"
decryption="AES"
/>
You can read to your heart's content at MSDN page: How To: Configure MachineKey in ASP.NET
Just generate <machineKey .../> tag from a link for your framework version and insert into <system.web><system.web/> in Web.config if it does not exist.
Hope this helps.
If you get here from google for your own developer machine showing this error, try to clear cookies in the browser. Clear Browser cookies worked for me.
in asp.net Core you should set Data Protection system.I test in Asp.Net Core 2.1 or higher.
there are multi way to do this and you can find more information at Configure Data Protection and Replace the ASP.NET machineKey in ASP.NET Core and key storage providers.
first way: Local file (easy implementation)
startup.cs content:
public class Startup
{
public Startup(IConfiguration configuration, IWebHostEnvironment webHostEnvironment)
{
Configuration = configuration;
WebHostEnvironment = webHostEnvironment;
}
public IConfiguration Configuration { get; }
public IWebHostEnvironment WebHostEnvironment { get; }
// This method gets called by the runtime.
// Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// .... Add your services like :
// services.AddControllersWithViews();
// services.AddRazorPages();
// ----- finally Add this DataProtection -----
var keysFolder = Path.Combine(WebHostEnvironment.ContentRootPath, "temp-keys");
services.AddDataProtection()
.SetApplicationName("Your_Project_Name")
.PersistKeysToFileSystem(new DirectoryInfo(keysFolder))
.SetDefaultKeyLifetime(TimeSpan.FromDays(14));
}
}
second way: save to db
The Microsoft.AspNetCore.DataProtection.EntityFrameworkCore NuGet
package must be added to the project file
Add MyKeysConnection ConnectionString to your projects
ConnectionStrings in appsettings.json > ConnectionStrings >
MyKeysConnection.
Add MyKeysContext class to your project.
MyKeysContext.cs content:
public class MyKeysContext : DbContext, IDataProtectionKeyContext
{
// A recommended constructor overload when using EF Core
// with dependency injection.
public MyKeysContext(DbContextOptions<MyKeysContext> options)
: base(options) { }
// This maps to the table that stores keys.
public DbSet<DataProtectionKey> DataProtectionKeys { get; set; }
}
startup.cs content:
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime.
// Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// ----- Add this DataProtection -----
// Add a DbContext to store your Database Keys
services.AddDbContext<MyKeysContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("MyKeysConnection")));
// using Microsoft.AspNetCore.DataProtection;
services.AddDataProtection()
.PersistKeysToDbContext<MyKeysContext>();
// .... Add your services like :
// services.AddControllersWithViews();
// services.AddRazorPages();
}
}
If you use Kubernetes and have more than one pod for your app this will most likely cause the request validation to fail because the pod that generates the RequestValidationToken is not necessarily the pod that will validate the token when POSTing back to your application. The fix should be to configure your nginx-controller or whatever ingress resource you are using and tell it to load balance so that each client uses one pod for all communication.
Update: I managed to fix it by adding the following annotations to my ingress:
https://kubernetes.github.io/ingress-nginx/examples/affinity/cookie/
Name Description Values
nginx.ingress.kubernetes.io/affinity Sets the affinity type string (in NGINX only cookie is possible
nginx.ingress.kubernetes.io/session-cookie-name Name of the cookie that will be used string (default to INGRESSCOOKIE)
nginx.ingress.kubernetes.io/session-cookie-hash Type of hash that will be used in cookie value sha1/md5/index
I ran into this issue in an area of code where I had a view calling a partial view, however, instead of returning a partial view, I was returning a view.
I changed:
return View(index);
to
return PartialView(index);
in my control and that fixed my problem.
I got this error on .NET Core 2.1. I fixed it by adding the Data Protection service in Startup:
public void ConfigureServices(IServiceCollection services)
{
services.AddDataProtection();
....
}
you are calling more than one the #Html.AntiForgeryToken() in your view
I get this error when the page is old ('stale'). A refresh of the token via a page reload resolves my problem. There seems to be some timeout period.
I found a very interesting workaround for this problem, at least in my case. My view was dynamically loading partial views with forms in a div using ajax, all within another form. the master form submits no problem, and one of the partials works but the other doesn't. The ONLY difference between the partial views was at the end of the one that was working was an empty script tag
<script type="text/javascript">
</script>
I removed it and sure enough I got the error. I added an empty script tag to the other partial view and dog gone it, it works! I know it's not the cleanest... but as far as speed and overhead goes...
I know I'm a little late to the party, but I wanted to add another possible solution to this issue. I ran into the same problem on an MVC application I had. The code did not change for the better part of a year and all of the sudden we started receiving these kinds of error messages from the application.
We didn't have multiple instances of the anti-forgery token being applied to the view twice.
We had the machine key set at the global level to Autogenerate because of STIG requirements.
It was exasperating until I got part of the answer here: https://stackoverflow.com/a/2207535/195350:
If your MachineKey is set to AutoGenerate, then your verification
tokens, etc won't survive an application restart - ASP.NET will
generate a new key when it starts up, and then won't be able to
decrypt the tokens correctly.
The issue was that the private memory limit of the application pool was being exceeded. This caused a recycle and, therefore, invalidated the keys for the tokens included in the form. Increasing the private memory limit for the application pool appears to have resolved the issue.
My fix for this was to get the cookie and token values like this:
AntiForgery.GetTokens(null, out var cookieToken, out var formToken);
For those getting this error on Google AppEngine or Google Cloud Run, you'll need to configure your ASP.NET Core website's Data Protection.
The documentation from the Google team is easy to follow and works.
https://cloud.google.com/appengine/docs/flexible/dotnet/application-security#aspnet_core_data_protection_provider
A general overview from the Microsoft docs can be found here:
https://cloud.google.com/appengine/docs/flexible/dotnet/application-security#aspnet_core_data_protection_provider
Note that you may also find you're having to login over and over, and other quirky stuff going on. This is all because Google Cloud doesn't do sticky sessions like Azure does and you're actually hitting different instances with each request.
Other errors logged, include:
Identity.Application was not authenticated. Failure message: Unprotect ticket failed

Why isn't my authentication cookie being set in MVC 4?

I've got an MVC4 project that I'm working on. When a user's login credentials are valid, I call FormsAuthentication.SetAuthCookie() to indicate that the user is logged in. (I have it wrapped in a class so I can mock the Interface for my unit tests.)
namespace FlashMercy.Shared.Security
{
using System;
using System.Web.Security;
public class Auth : IAuth
{
public void SetAuthCookie(string userId, bool remember)
{
FormsAuthentication.SetAuthCookie(userId, remember);
}
public void Signout()
{
FormsAuthentication.SignOut();
}
}
}
In the debugger, I can confirm that the .SetAuthCookie(userId, remember) line is executing, and userId is populated.
Then, I have a custom authorize attribute to check that the user is logged in:
namespace FlashMercy.Shared.Security
{
using System.Web.Mvc;
public class FlashMercyAuthorizeAttribute : AuthorizeAttribute
{
public override void OnAuthorization(AuthorizationContext filterContext)
{
if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
{
filterContext.Result = new RedirectResult("/");
}
}
}
}
When I debug the application, the filterContext.HttpContext.User.Identity.IsAuthenticated is false even after I've supposedly set the auth cookie. Also, filterContext.HttpContext.User.Identity.Name is empty. I'm not sure what I'm missing here.
Update
If you care to look at the whole source, it's available on GitHub: https://github.com/quakkels/flashmercy.
Problem with your code is that you are using FormsAuthentication, but you didn't add it to web.config. Your web.config should have such section:
<system.web>
<authentication mode="Forms"></authentication>
...
</system.web>
Based on this Mode Asp.Net understand what authentication mode it should use, e.g. Forms, Windows, etc. And without settings it to Forms value - FormsAuthenticationModule just ignores .ASPXAUTH cookie from the request.
PS. I've downloaded your code, and with correct authentication section in web.config it works fine and updates HttpContext.User.Identity.IsAuthenticated to true.
The problem is that you only set the authentication cookie but do not have anything that load it.
It's forms authentication that uses that cookie. So you either have to activate forms authentication or you'll have to load it yourself.
filterContext.HttpContext.User.Identity.IsAuthenticated is false even after I've supposedly set the auth cookie.
This will always be the case if you do not redirect after SetAuthCookie(). The ASP.Net pipeline is in charge of authorizing the user (most of the time before we write code) in the AuthenticateRequest. Setting a Cookie does not update the current User.Identity, this requires code that has already been executed. Just make sure anytime you SetAuthCookie() you immediately redirect (server side is fine) to another URL (probably should anyway, its a good way to seperate logging in a user, and what they should do next SRP).
