This has come up for me again... this time I need to "scrub" some unique data in the origin reponse, cache it, and put something else back in it's place on the way out.

I'm guessing based on previous questions I've asked on this forum that this is not possible.

Best I can tell, this is the sequence of events: 

May  5 13:29:33 local/tmm1 info tmm1[5096]: Rule events : CLIENT_ACCEPTED
May  5 13:29:33 local/tmm1 info tmm1[5096]: Rule events : HTTP_REQUEST
May  5 13:29:33 local/tmm1 info tmm1[5096]: Rule events : HTTP_CLASS_SELECTED
May  5 13:29:33 local/tmm1 info tmm1[5096]: Rule events : SERVER_CONNECTED
May  5 13:29:33 local/tmm1 info tmm1[5096]: Rule events : HTTP_REQUEST_SEND
May  5 13:29:33 local/tmm1 info tmm1[5096]: Rule events : HTTP_RESPONSE
Where in here does stuff get sent to WAM?

Is there a way to mess with the "priority" to get at it before it goes to cache?
