Other information:

Security features. Do not change this feature unless you are sure of the scope of the change. You must detect a network trace before changing the value to ensure that the request is not potentially malicious. If double escape sequences are allowed on the server, change the configuration/system.webServer/security/requestFiltering@allowDoubleEscaping setting. The problem could be caused by an invalid URL sent to the server by an attacker.
