Can Irule forward request after ASM block?
Below is a snippet from an inquiry I received from our web developers. Matching on part of the URI is no problem, but what about forwarding the request even after blocked by the ASM?
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
So the iRule would have to match on:
- Portions of the URI that indicate this is an FNOL
- That the ASM blocked the request
Then:
- Forward the buffered request to a specific URL
Assumptions:
- The iRule can buffer the request so it persists beyond the ASM block. This alone may be the show-stopper as this may be a significant performance problem.
- The iRule can send to a different location than just allowing to pass to the back end pool members
