Problem with Web services

[salman.rahmat]

hi there
I am using MapPoint Webservices in my navigation application using
VS2003 and some others using VS2005. The problem is that when I call a
web service sometimes it gives me the results (rarely) and often it
gives me the error of time-out.
I searched about the probelm and found in some resources that I can
increase the time out and I did that, however, a new problem came in
front of me now saying:

The underlyig connection was closed. An unexpected error occurred on a
receive.

I have no idea what is going on. I have checked the same application in
other computers and it gave me the same error.

Anyone faced the same problem?

There are quite a few potential causes for this -- I've seen it mostly from
buggy firewalls that don't handle HTTP 1.1 correctly.

Here's a link that may help you identify the problem:

I've successfully used Resolution D (and also changing the HttpWebRequest's
ProtocolVersion to HttpVersion.Version10 in some cases) to get more reliable
connections past some of the bad proxy/firewalls.
