System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send.

When I invoke two web service methods sequentially with no delay, the
first web method invocation goes smooth while the 2nd one generates the
dredded:

The only way I have been able to make consecutive web method invocations
work is by overriding GetRequest and disabling Keep-Alive. The IIS
Keep-Alive setting is enabled for 120 seconds but yet it appears that
value is not being honored by IIS for some reason. I would rather not
disable keep alive to make things work as doing so has network performance
implications. Has anyone gotten Http Keep-Alives to work in .NET 2.0?

Ok, for anyone interested, I solved the issue. At the time of the
WebException, I happened to be running Fiddler 2.0.9.0. Fiddler
automatically reconfigures IE proxy settings to support HTTP tracing.
Apparently, this version of fiddler has issues with HTTP-Keep alive. I
turned off Fiddler, re-ran my code and all is well.
