.NET Forum / .NET Framework / New Users / September 2004HTTP 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! /peter 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)..

" 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 http://blogs.msdn.com/gzunino/archive/2004/09/05/225881.aspx SignatureGreetings Jochen My blog about Win32 and .NET http://blog.kalmbachnet.de/ Hi and thanks for the tip! How can one see if sp1 is installed (what version shows up in the .NET Configuration)? /peter > > Hi > > [quoted text clipped - 12 lines] > HTTP response split attacks, HttpWebRequest and the NET Framework 1.1 SP1 > http://blogs.msdn.com/gzunino/archive/2004/09/05/225881.aspx Free MagazinesGet these publications absolutely FREE for up to 12 months.
