How to Fix HTTP Error 404.11 – Not Found: Request Filtering Module Configuration

HTTP Error 404.11 – Not Found

The request filtering module is configured to deny a request that contains a double escape sequence.

Most likely causes:

  • The request contained a double escape sequence and request filtering is configured on the Web server to deny double escape sequences.

Things you can try:

  • Verify the configuration/system.webServer/security/requestFiltering@allowDoubleEscaping setting in the applicationhost.config or web.confg file.

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.
