If you use RSS Bandit and recently installed .NET Framework 1.1 SP1 you may have noticed that you started getting errors of the form

Refresh feed 'SomeCategory\SomeFeed' failed with error: The underlying connection was closed: The server committed an HTTP protocol violation.

This is due to changes made to the System.Net.HttpWebRequest class to make it more compliant to the HTTP specification. For example, it now errors when fetching the Microsoft Research feeds because the web server returns the Content-Location header as "Content Location" with a space. The fix is straightforward and involves placing the following element as a child of the configuration element within the rssbandit.exe.config file in the C:\Program Files\RssBandit folder.

  <httpWebRequest useUnsafeHeaderParsing="true" />

This is also taken care of by v1.2.0.117 of RSS Bandit. When running it detects whether this option is available and enables it automatically so you don't have to mess around with XML configuration files.
