Maximum request length exceeded

ASP.NET by default has a limit of 4 MB of file upload. In order to bump up this limit, web.config needs to be updated. Below is example to allow 1 GB of file upload (1 GB = 1048576 KB = 1073741824 Bytes).

<configuration>
 <system.web>
  <httpRuntime maxRequestLength="1048576" />
 </system.web>
</configuration>

For IIS 7 or later, the following is also needed. Max size value in KB and Bytes must match in both places.

<system.webServer>
 <security>
  <requestFiltering>
   <requestLimits maxAllowedContentLength="1073741824" />
  </requestFiltering>
 </security>
</system.webServer>

In order to specify execution timeout, add executionTimeout value in seconds as follows.

<configuration>
 <system.web>
  <httpRuntime maxRequestLength="1048576" executionTimeout="3600" />
 </system.web>
</configuration>
