Outbound HTTP Connection Bottleneck

Peter Burke

7/9/2003 11:53:00 PM

I'm consuming a web service via the internet from a web
service client proxy running on my webserver. The web
service provides data for individual client sessions. I've
observed via netmon, that my outbound HTTP requests are
limited to two, with the rest being queued. Two out, two
responses, next two out...

Has anyone run into this problem? If so, did you fix it or
work around it? It's a serious bottleneck. This is known
to happen with the XMLHTTP object. I just can't figure out
where in the class libraries this is being used, or how to
override it.

This is well known problem. Actually this is restriction of HTTP
protocol (if you want I can give you even quotation from the HTTP
specification).

There is such thing like "DefaultConnectionLimit" try to play with it.
Take a look at the following topic ".NET Framework/
Programming with the .NET Framework/Using Application Protocols/
Managing Connections" in MSDN.

Hope this help.
