irule vs LTM policy

Policies and profiles always execute before iRules for the same network layer.

For example we have policy to ensure iRules events are enabled as we have several iRules that do an

event disable all

during select errors, to ensure we re-enable all the iRule event for the next HTTP request (multiplexed clientside connections) we use policies to run the TCL commend to

event enable all

. We can only do this as the Policies execute before our iRules.

However, your

CLIENT_ACCEPTED

iRule event will execute before your HTTP profile or any Policy looking at the HTTP request as this is simply the order of events based on the F5 processing through the network layers.
