Today I have encoutered a problem with debugging my web projects in Visual Studio 2005. The message was:
"Unable to start debugging on the web server. The server committed a protocol violation. Section=ResponseStatusLine".
I haven't changed anything in my software configuration since the beginning of the procject so I thought that something may be wrong with my IIS. I have searched the Internet for the error message and I have found the following article describing the problem. Basically it was Skype that made a conflict. I have done as the author suggests and it worked! Many thanks to Martin for investigating the issue. Just remember to start the IIS after changing options in Skype because it is now running (at least such was my case).
The strange thing is that I have allwasy have Skype running so why it conflicted today and not before? Strange...
