How to increase request timeout in IIS?
Add this to your Web Config

Optional TimeSpan attribute.
Specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET.
This time-out applies only if the debug attribute in the compilation element is False. To help to prevent shutting down the application while you are debugging, do not set this time-out to a large value.
The default is "00:01:50" (110 seconds).
In IIS Manager, right click on the site and go to Manage Web Site -> Advanced Settings. Under Connection Limits option, you should see Connection Time-out.
