HTTP::respond from HTTP_RESPONSE with ASM

I'm considering writing an iRule to detect 404s and 500s. I think I'd like to send the user to a hold page that shows the request they made, explains that it was invalid, and then after 5 seconds or so, send them to a legitimate page. Reading the SOL article below makes me think that because I'm using ASM, I need to disable it as part of the rule.

Thoughts?

    Hi Chris,

     

     

    That seems doable. You'd probably want to set 404 and 500 to allowed in the ASM policy to prevent ASM from marking the responses as illegal and blocking them.

    Definitely seems necessary to use ASM::disable and ASM::enable though from within the rule?

    Sorry, I was thinking the ASM plugin gets the response before HTTP_RESPONSE. But you're right that HTTP_RESPONSE is triggered before ASM gets the response. So you would want to disable ASM and at that point it doesn't matter what is configured for response status code checking in the policy.
