We recently enabled Content Redirection in URLScan 3.1 on our IIS 6 server. I have filtered out (whitelisted) all of the pages that have Insert, Select, etc in the URL/file name.

That said, I am getting a .NET error when trying to add a YouTube video to an editable text box:

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
