AsyncFileUpload Change Request Size

Question

I am currently working on an ASP.net C# web app. I am using the AjaxControlToolkit ASyncFileUpload, however, when I upload a certain file I get the error message Maximum Request Length Exceeded. Is there a way that I can increase the size limit for file uploads.

Thanks for any help you can provide.

The maximum request length is set in web.config, specifically in the httpRuntime/maxRequestLength value.

<!-- Maximum 16 MB -->
<httpRuntime maxRequestLength="16384" />

Do be aware that there might also be a limitation in IIS depending on your version.

Max request length is defined in web.config in KB as 4096 (default to 4MB), you can change the following in web.config

   <system.web>

  <httpRuntime maxRequestLength="51200"

  enable = "True"

  executionTimeout="45"/>

  </system.web>

 </configuration>
