The default proxy settings in .NET 2.0 are a bit different than in 1.x. By
default .NET 2.0 uses the default proxy which is using the IE settings
installed in the registry. Since ASP.NET by default doesn't have access to
those keys it ends up searching around for the proxy settings and fails
which is what's very slow.

> Hi,
> Hope someone can help us with this problem. This is our first endeavour
> into .NET 2.0 :-)
> BACKGROUD INFO:
> ----------------------
> We've built a website using .NET 2.0 and deployed onto our webserver. This
> webpage simply calls some web services (built with .NET 1.1) running on
> the
> same web server. The webservice executes SQL transactions to a SQL Server
> which sits behind our company firewall.
> PROBLEM:
> ----------------------
> Everytime a form is submitted (a web service call happens here), it's
> trying
> to connect to a proxy server which no longer exist!! This was verified by
> our
> network team. (Please see below for error message and stack trace).
> OTHER NOTES:
> ------------------
> Numerous pages have been built using .NET 1.1 running on the same
> webserver
> and we've never encountered this problem.
> TESTING DONE:
> -------------------
> To test that it's not something wrong with the webservice, we've built a
> simple web page using .NET 1.1 which calls the same webservice, depoyed it
> onto the webserver, a request was made, and it was successful.
> We've also ran this website in question from a internal webserver, and did
> not encounter this problem.
> QUESTIONS:
> -------------------
> 1)Is there any differences in the way a ASP.NET page built on .NET 2.0 and
> .NET 1.1 makes it's call to a webservice??
> 2)Where is the ASP page picking up this proxy settings from? ASPNET
> account??
> 3)Is there a way to overcome this proxy problem from our ASP.NET code?
> Many Thanks,
