.net MVC 2 default Route suddenly stopped working - asp.net-mvc

today the default route for my site stopped working, but the strange thing is that the global.ascx has not changed at all.
when i enter the URL mysite.com/
i get this 404 error
The resource cannot be found.
Requested URL: /Views/Start/Index.aspx
i have a bog standard default MVC route
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Index", action = "Index", id = "" }
);
the oddball thing is that even if i create a Start folder with a copy of my index view, it still doesn’t work and throws the same 404 error.
has anyone else had this issue ??
any help is most appreciated

Re-add ASP.Net MVC's default Default.aspx file to the site root.
This file forces requests to / to run through the routing engine.

Although not necessarily the answer to this question, when Haack's debugger is showing that your routing tables are set up fine but you're still getting 404s, check your Controller is public!

Remove "Home/Index" secondary route to home page

I have an ASP.net MVC 5 site. The home page is at http://mydomain.
However, there's also a second route to the home page - http://mydomain/home/index - which I think
This causes problems because it may be seen as duplicate content, and images are broken on this page.
How can I totally remove this route (so it goes to a 404, I guess?).
I've searched Google but can only find articles on removing Home from routes entirely - not what I need.
I'm using Attribute routing, and this is all that's in the RouteConfig.cs:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
// Enable Route Attributes in Controllers
routes.MapMvcAttributeRoutes();
// Fall through all routes
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
The Home Index action has no attribute route on it (as you'd probably expect?). This /home/index route works even on newly generated MVC projects - which I think is a bad idea?
How can I do this?
Are there any problems with removing this route I may not have considered?
thx.
You can block unintended routes that you don't want by using IgnoreRoute().
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("Home");
routes.IgnoreRoute("Home/Index");
// Enable Route Attributes in Controllers
routes.MapMvcAttributeRoutes();
// Fall through all routes
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
However, if these URLs are already in the wild, you should instead setup a 301 redirect to the canonical URL you intended. The simplest way to do that is with the URL rewrite module.
This /home/index route works even on newly generated MVC projects - which I think is a bad idea?
I see this as more of a blessing in disguise. It is an advantage over any SEO competitor using MVC who doesn't do the extra work to remove these routes when you are the one who does.
This is not necessary.
The default route provides optional controller and action names. So if user does not put any name for controller and/or action in path (/Home/Index or /Home in this situation) asp.net will put the right values in application routing.
Whenever you use Url.Action or Url.Route functions it will produce the shortest link for you. So in your website there will be always http://mydomain produced for your root. And for example Category > Index action it will produce http://mydomain/category.
In your website bots will never get to duplicate content if your links are in this way. If you are writing your links manually write as short as you can or simply use Url.Action.
About the images there must be something different, because images are static files. just use "~/imagefolder/imagename.jpg" way to get them. "~" is important to start link from the root of application if you are making your application work on a subfolder in IIS.

ASP .NET MVC RedirectoToAction ignores the application where is located

I have a MVC application deployed in my server in a virtual directory like:
http://localhost/myapp/
Where "myapp" is the virtual directory
In my Login view, located in
"http://localhost/myapp/user/login",
I redirect to the index using RedirectToAction("Index", "Home"), it seems the application try to redirect to
"http://localhost/home/index"
instead of
"http://localhost/myapp/home/index".
The application works when it's located in the root of the IIS Web Site but doesn't work in the given situation.
It's there a way to configure the application root, that I missed?
Settings: Microsoft Visual Studio Express 2012 for Web, IIS 7 under Windows 7 , application pool ASP .NET v4.0
I am 99% positive that doing:
return RedirectToAction("Index", "Home")
is application root relative meaning that it should redirect to the application you're in regardless of the virtual directory settings or where the application is located. I mean think of the nightmare otherwise that every time you move the app to a different virtual directory you need to update the global.asax or web.config file??? Ridiculous! We have the same setup that you have and we have no issues with "app hopping."
Are you sure that RedirectToAction is causing this? Could it be that you have something like:
#Url.Content("/Home/Index")
In that case you would experience this issue and you can easily fix this by doing:
#Url.Content("~/Home/Index")
~ symbol makes it application root relative...
thats correct functionality. MVC will calculate the route as controller/action by default.
If you want this to do otherwise you need to add a route into the Global.asax:
//this is your new route which needs to be ABOVE the detault
routes.MapRoute(
// Route name
"myapp_Default",
// Url with parameters
"myapp/{controller}/{action}/{id}",
// Parameter defaults
new { action = "index", id = UrlParameter.Optional });
//This is the default route that should already be there.
routes.MapRoute(
// Route name
"Default",
// Url with parameters
"{controller}/{action}/{id}",
// Parameter defaults
new { action = "index", id = UrlParameter.Optional });

ASP.NET MVC2 Routing IIS6 - only default routes work

I've deployed an ASP.NET MVC2 website on a Windows Server 2003 machine running IIS 6.
I'm using pretty much the default routing in a standard MVC project:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Products", action = "List", id = UrlParameter.Optional } // Parameter defaults
);
}
Navigating to http://localhost/MyApplication takes me to the List page just fine. Navigating to http://localhost/MyApplication/Products/Details/21 gives me a 404. This routing worked fine on the inbuilt development server in VS2010.
I've put in the standard IIS wildcard aspnet_isapi.dll mapping mentioned all over the place - navigating to the List page didn't work before I did - but navigating to anything other than the default route is broken.
I'd really like to keep my extensionless URLs. Does anyone have any idea as to why the routing would work for the default webpage, but no others?
*Edit: just tried adding the .aspx extension, ie now my route looks like this:
routes.MapRoute(
"Default", // Route name
"{controller}.aspx/{action}/{id}", // URL with parameters
new { controller = "Downtime", action = "List", id = UrlParameter.Optional } // Parameter defaults
);
And it has the same behaviour, except this time I get the asp 404 page instead of the html 404 page...
*Edit 2: tried it again using the following route and making sure .mvc was mapped to aspnet_isapi.dll:
routes.MapRoute(
"Default", // Route name
"{controller}.mvc/{action}/{id}", // URL with parameters
new { controller = "Downtime", action = "List", id = UrlParameter.Optional } // Parameter defaults
);
This time I got an 'Internet Explorer cannot display the webpage' 404-style page. I've now got 3 different 404 errors from using these 3 different methods...
*Edit 3 Return of the Edit: I have the site running in IIS 5.1 on Windows XP professional with only a wildcard remapping on the virtual directory, but heaven forbid I can get it to run on the webserver...
First of all, you should follow this walk-through: http://haacked.com/archive/2008/11/26/asp.net-mvc-on-iis-6-walkthrough.aspx
(just to make sure you've not missed something). This shows how to get the extension-less and extention'd versions working. You might want to at least check whether the extension'd version works to check that other things aren't misconfigured.
After that, perhaps you should try adding something like this..
http://haacked.com/archive/2008/03/13/url-routing-debugger.aspx
... as it can really help in determining where your routes are broken.
Some other things to check:
Is IIS configured with ASP.NET? Check properties of the virtual directory. On the VDir select the configuration button and check that the usual ASP.NET extensions are mapped to the .NET 2.0 ISAPI dll. This will be something along the lines of
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll.
Is ASP.NET 2 enabled on IIS (under IIS 6 this is off by default): in IIS manager check the Web Service Extensions folder to enable it.
Have you deployed global.asax?
Found it - the routing is actually working, my URLs were not. I was using javascript to build some of the URLs and it turns out that I wasn't linking to
http: //localhost/MyApplication/Controller/Action/ID
I was actually linking to
http: //localhost/Controller/Action/ID
Building the links like this was working on the development server, but once the site was deployed to a virtual directory on the webserver those addresses are incorrect because of the extra application name in the URL.
In conclusion, be careful with your URLs - don't build them out of strings like I did.

ASP.NET MVC - Running in a Subdirectory

I am attempting to deploy an ASP.NET MVC application in a subdirectory of an existing application and I am running into some routing issues. I have set up the folder structure such that all of the binaries and config files for the MVC app are correctly located in the root directory, while the rest of the content is in the subdirectory. Additionally, I updated all of the routes in the MVC application to reflect the subdirectory; however, every request to the application produces:
The incoming request does not match
any route.
All defined routes are being ignored, including the default route:
routes.MapRouteLowercase(
"Main_Default",
"blog/{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = "" }
);
I tried enabling RouteDebug to test the issue, but even that is not getting routed to. Any advice on what else I can try?
Note: This question is not a duplicate.
Try running it as a virtual directory instead of just a directory, otherwise your routes are not going to be called. You will not need to put the name of the virtual directory in the route.
Here's a route that I have setup in a v-dir MVC app that works just fine...
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Tour", action = "Index", id = "" } // Parameter defaults
);
Looks like I found the problem.
In addition to the binaries and the config files, Global.asax must also be placed in the root in order for its code to be executed.
Thanks guys. :)

Strange route problem in ASP.NET MVC - default route not hit

I have this two routes currently in my application after decommenting out many other ones. Let me first explain that I have quite a big application already but have come to a problem where my application does not start at the root url anymore.
If I set starting page to default.aspx then webapp starts at (example) http://localhost:55421/Default.aspx. I don't want that. I want it without Default.aspx
So I went into app properties and removed Default.aspx as starting page - now it is blank field (just like in a sample new MVC app if you create it in VS 2008).
But now application does start at the required URL but issues an error:
"The incoming request does not match any route."
Also If I use route debugger it also misses all routes and catches it by catchall route.
I don't know how all of this is possible since as I said above I have two default routes configured at this time:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default",
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Pages", action = "Display", slug = "Default" }
);
Any help appreciated
Am I right in thinking you are trying to hit
http://server/{controller}/{action}/{id}
with
http://server/
If you are I think you need to provide a default for the last parameter {id}. You have a default for a parameter slug but without a default for {id} I don't think ASP.NET Routing can hit it.
If I'm right
http://server/Pages/Display
should also not hit the default route, because you are expecting id in Display?
HTH
