I have problem with rewriteMaps in Web.config. My rewriteMaps section is in separate file, something like this configSource="webConfigRules\rule1.config". It's working, but only for static rules. I would like to make changes and refresh whole rewriteMaps section without server restart. It is possible?
IIS will recycle the application pool when your web.config file changes but not for the rewrite rules file. You can either manually recycle the app pool or force a recycle using another method. This answer gives a good explanation if you need more information Does any change in any file inside bin folder cause application recycle in ASP.NET web application?

I have asp.Net MVC web application deployed on azure. And have some problems with Slow HTTP POST vulnerability. So I want to configure <\limits> to turn on connectionTimeout.
I can`t do this in Web.config (or mb just don`t know right place to write it).
In guides this thing configure on iis, but how to do this in azure?
The setting that you are talking about connectionTimeout needs to be set in the applicationhost.config file. This file is not found as part of your project, but is part of your azure website. If you want to view the configuration settings in this file you can go to the kudo service for your site which can be accessed by following the directions here:
https://github.com/projectkudu/kudu/wiki/Accessing-the-kudu-service
To get to the location of the file go to the cmd console, click on the globe icon and it should be in the the Configure folder. That is how you view the current settings. To actually change the settings you need to create an xdt transform file and drop it into your site root and restart the site. This can be done using ftp (the ftp host url can be found in the azure portal for you site).
You are also going to want to configure your <\webLimits> as well to help prevent a slow post attack.
I have only few projects on my bag. In a previous desktop application when I wanted to store and use some application specific information I was using the app.config file.
Now I work on ASP.NET MVC 4 application and again I want to store some application specific information but this time I'm not sure. I have the web.config file which seems like a good place for this purpose but I'm not sure if it's the right place to store custom information there.
What is the right approach to do this? For example I want to save and extract path to directory on the file system where I'll save all my files. In ASP.NET MVC 4 what/where is the right place to do that?
The web.config file is what web application use where a desktop application uses app.config, and it's a good place to put application specific information.
You can add keys to the <appSettings> tag, and use them in the application just as you would if you put them in that tag in the app.config file. Example:
string path = ConfigurationManager.AppSettings["DataPath"];
Web.config is for ASP.NET and ASP.NET MVC; app.config is for desktop applications and DLLs.
If you need to storie any kind of parameter for your application that you can change without having to recompile, Web.config is the place to go.
Web.config is the web application version of app.config. Web.config seem like a good place for the configuration settings you're talking about.
Sometimes when you have a dll that had reference to desktop app.config, and when you import that MVC application you need to change the configuration data that used to be in app.config now to web.config.
need your help with this one, i'm running azure deployment on my localhost and get the webpage without css and javascript, when i look in fiddler i see 500 status and the following error: "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS" on each request for javascript or css file, i already enabled static content on windows feature and it didn't help, i'm using iis 7.5 on windows professional 64 bit with azure sdk 1.7, tried anything, and nothing helped, can't change the site to web application cause the website only exist on iis while i'm running debug, any idea what to do?
Could it be that the directory from which you're serving JS/CSS files contains a web.config file? If this is the case this will be causing the problem.
Your web.config contains an element which can only be defined in a real web application (in the root of your application for example- or in the machine.config. To fix this issue you'll need to open the machine.config (C:\Windows\Microsoft.Net\Framework\v4.0.30319\Config\machine.config) and look at each configSection defined here that is also included in your web.config (in the folder containing the JS/CSS files).
If the configSection in the machine.config contains the allowDefinition attribute with MachineToApplication as value this means you cannot use that configSection in a web.config that isn't located in a web application. Meaning in your case you'll need to remove that configSection from the web.config in the folder containing the JS/CSS files.
If you're using ASP.NET MVC this is probably your Content folder.
I have an ASP.NET webapp using the ASP.NET MVC 2 framework. It allows users to upload files to an uploads folder. The issue occurs when an image within a sub-folder is accessed by a web browser:
http://mywebapp/uploads/image_gallery/sub_folder/image.jpg
The uploads folder is static and can't be modified by users, but anything below it is intended to be modifiable.
In the above example, the image_gallery folder becomes locked because w3wp.exe appears to create a handle on the sub_folder directory (using process explorer by sysinternals). I am still able to rename the sub_folder directory and the handle seems to stay with it after a rename, but i can't rename the parent folder (image_gallery in this case).
I can still browse within the folder and view other images and files etc. But can't rename the parent folder.
As this is using the MVC 2 framework i've put in an exclusion for the uploads folder like so:
routes.IgnoreRoute("upload/{*pathInfo}");
into global.asax, so i'm assuming that ASP.NET is serving up those images directly (outside of the MVC framework)
So I guess my question is, is there any way to prevent IIS from putting a handle on specific directories or forcing it to remove a handle? Is the MVC 2 framework doing something tricky even though i have the ignoreroute specified?
Thanks in advance for any tips!
I had the same problem, and after much investigating I've found the culprit:
Web.config
<configuration>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
Setting this option (which makes all http modules run on ALL files, static ones included) to false fixed it for me.
I believe, directory handle gets created in worker processor because ASP.NET typically watches the file system for changes - this allows it to respond to change/addition of config files, new dlls etc.
I suggest that you move from the concept that users can control physical directory structure on the web server. Typically, what user can create is an logical directory structure but physical structure would be controlled by your program logic. Your logic will store the logical structure created by user and its mapping with actual physical structure on the web server.
In my MVC application ,I am updating my web.config at runtime through application_start event.So, ideally it should be done only when the application is started.BUT in MY mvc application the application_start event of global.asax is being called multiple times , even when i have not restarted the application.
Its being repetadly called when i am calling different actions , so the webconfig is repetedly updating & making my application very very slow.
Can you please let me know , what's the reason & how to handle this .
Thanks in advance

Everytime you change something in your web.config. That will refresh your application, therefore application_start is also called everytime you open your site. When web.config is changed, your application restarts.
I dont know which elements in your web.config you are updating. If these are custom elements maybe you can put these things in a separate config file (xml file) and update that file.
You application will be restarted once web.config is modified.
It doesn't make any sense changing web configuration file in application_start. Moving changeable part into a separate file
