Tcpclient problem with proxy server

[Tamas Bojcan]

Hi,

I use TcpClient class to obtain a NetworkStream object (via TcpClient's
GetStream() method) in an ASP.Net webapp. This works well if I'm not behind
proxy server but if I'm connected to the network via proxy server I get
"dead network..." error message during the creation of the TcpClient object.
The most strange thing is that the same code is works well with proxy too if
it is in a single C# project. What's the problem in case of ASP.Net?
Thanks!
