I\'m seeing this on our production site as well as a small test site I setup just to test this out...
Basically, it appears that requests handled by mvc never time out.
It should work when these conditions are met:
1) Domain name is not localhost (to test timeout you should use "YourComputerName" instead of "localhost").
2) Project is compiled in Release mode.
3) compilation debug="false"
if not look here for an alternative (ScriptTimeOut): ASP.NET MVC and httpRuntime executionTimeout
