Deep ASM logs

How can we know the reason why ASM is blocking a URL ? Can we have more details on the blocking reason ? Which part of the URL is causing problem ? In ASM logs on the F5 I was not able to find this. ...

Usually this can be extracted using the Support ID displayed on your browser while the request is blocked, from the ID if you have V13 software you may go to the security tab-->Event Logs-->Application-->Requests, and filter by the Support ID you got.

 

Hope this is helpful!

Yes I checked but the only reason is multiple encoding, so it doesn't help so much to find the real reason for this blocking, maybe we should check ASM logs on CLI to have more details
