Error 404.13 The request filtering module is configured to deny a request IIS

Hello folks,

          You might have encounter an error while uploading files to the server

"The request filtering module is configured to deny a request that exceeds the request content length"

so what does this error actually means, and how to solve this error..

Basically IIS has defined a size limit for uploading file, by default the size limit is 30000000 bytes i.e. 28 MB. So when ever a user try to upload a file that is larger than 28 MB this error will come up.

In order to fix this problem follow these simple steps.

1. Click on start button and type inetmgr, this will open up the IIS Manager

Alternatively you can go to 

Control Panel >> Administrative Tools >> Internet Information Services (IIS) Manager 

     
     2.  Now from the right side window Double click on Request Filtering

     3.  Now Goto Rules Tab

     4.  Now right click and select Edit feature Setting

     5. Now set the "Maximum Allowed Content Length" according to your requirement

   
      6. Click on OK to finish

Note: It is recommended to restart the IIS after setting the value.

Error 1935 while installating Visual Studio

Hello,
         Today while installing Visual Studio 2010 on my windows 7, I encountered an error

 Error 1935. An error occured during the installation of assembly 'VsWebSite.Interop,version="8.0.0.0",publicKey Token= "b03f5f7f11d50a3a",fileVersion="8.0.50727.932",culture="neutral"'. Please refer to Help and Support for more information. HRESULT: 0x80070005

I was curios to find what the actual problem in, because I had never received this kind of error before. So after a little bit of search I found that Error 0x8007005 indicates that

the setup was not executed with Administrator rights. 

This problem may comes up when you already had some features of VS installed, especially on windows 7

So I re-started the setup by right click and choose Run as administrator, and the whole setup went fine.

How to Redirect from Non-Exist url to a Existing One C#

Hello Everyone today I’m gonna teach you, if the user type a URL that doesn’t even exist, so how to rediect them to a Existing Page without showing them the default 404 Error Page.

We will use the web.config file for this purpose, this can also be done in IIS via URLReWrite

1. First Add 2 webpage and name them home.aspx and Error.aspx
2. Now open your web.config
3. Find <System.Web> tag
4.  Now place the following code inside the <System.Web> tag

   <customErrors mode="On">

   <error statusCode="404" redirect="Error.aspx"/>

   </customErrors>

This code will check the url , if the url exist than this code will do nothing, but if the page doesn’t exist it will rediect them to Error.aspx page.

Note

•  Error Code 404 means Page Not Found
• You can Change the StatusCode according to your requirements
• If CustomErrors mode is set to Off than this rule will not do anything

Browser StatusCodes 

• 1xx Informational
• 2xx Success
• 3xx Redirection
• 4xx Client Error
• 5xx Server Error
