HTTP violation

Hi

I've made a part of a program that makes a http web request with .net
classes HttpWebRequest and HttpWebResponse. It's been working fine up til
now when one of our customers has been recieving the following WebException:

"The underlying connection was closed: The server committed an HTTP protocol
violation. "

I've been "googling" a bit and read that it might help to set the KeepAlive
property to false and set the http version to 1.0, but neither have helped.


Thanks in advance!

You might want to run a HttpTrace or some such HTTP traffic capture program
to see what kind of requests are going across the wire. (for the ones
working and not)..

Hi,
that is kinda hard. I do not have access to the computer with the problem,
but he's agreed to try the patches I'm emailing him.

Is it running under .NET 1.1 SP1 !?

Then here might be the reason:

HTTP response split attacks, HttpWebRequest and the NET Framework 1.1 SP1

Hi and thanks for the tip!

How can one see if sp1 is installed (what version shows up in the .NET
Configuration)?
