Dear all bro, we are facing problem with out Baracuda WAF 960 (firmware version v10.0.0.010)

The WAF blocks method DELETE and recommend a fix:


The request used the method DELETE which is not in the list of Allowed Methods defined in the Security Policy under URL Protection,or in the list of Allowed Methods in the URL profile that matched by the URL /chatserver/api/ChatConfig/12.


Create a new URL Profile for URL /chatserver/api/ChatConfig/12 and add the method DELETE for the website ....


we have fixed as the recommendation, and retry. But is still error and this time: there are no Web Application Firewall DENY Log but in Access Log, there are still the log: 405 - Method not Allowed.


Note that if we connect directly to the web server, everything will be OK.


So could anyone face the same issue? I really appreciate for your help :)

By any chance, do you have JSON Security turned on, and does the request come in with the "Content-Type: application/json" header? In such a case, the WAF will  process the request as per the JSON profile, where DELETE may not be part of the allowed request.
