SocketTimeout: Read timed out

I'm using Flex - IIS - ASP.NET to do remote calls. When I stresstest, all remote calls that take longer than 30 seconds fail. In Charles I get a message saying 'SocketTimeout: Read timed out'. Is this something that can be configured in IIS? Or could it be a problem w开发者_如何转开发ith a setting in Charles?

No clue what Charles is....

...but you know that ASP.NET has a script timeout limit that is 30 seconds per default (but you can change it, even in code in the page)?
