When you have a large download

In .NET 1.x there is a default maximum download time of 90s and for > 2.x this is 110s.  However, this only applies to release code (debug=”false”) so make sure to test in release mode too!

In some circumstances, such as when serving a large file from .aspx, you may want to increase this.

This can be done using the executionTimeout attribute httpRuntime element in the web.config.

Example – set the timeout to 10 minutes:

 

<configuration>

  <system.web>
  <httpRuntime executionTimeout="600"/>
  </system.web>

</configuration>

This cannot be set on an individual page with a location tag but can be done in a directory with a web.config in that directory.
