More Information:

This is a security feature. Do not change this feature unless the scope of the change is fully understood. You should take a network trace before changing this value to confirm that the request is not malicious. If double escape sequences are allowed by the server, modify the configuration/system.webServer/security/requestFiltering@allowDoubleEscaping setting. This could be caused by a malformed URL sent to the server by a malicious user.
