Hi there,

 

 

Out of curiosity, why are you trying to do this?

 

 

Testing with a simple iRule on 9.4.5HF2, I see HTTP_RESPONSE being triggered when a request is blocked. None of the headers are logged as they would be in a normal response from the pool.

 

 

I'd suggest opening a case with F5 and ask them why this is and whether there are any plans for supporting modification of the headers and/or body for ASM blocking responses.

 

 

Also, I'd strongly suggest upgrading to 9.4.5HF2 as there have been a lot of major issues fixed in the latest version and hotfix.
