    First, the assignment needs to be [HTTP::method]

    Your irule just needs to reference the connection variable that you assigned in the policy

    when HTTP_REQUEST {
  log local0. "$policy_http_method"
}

OK, my bad, I found it... of course I had to put the logging policy rule on top in the policy list !

It's working now, thanks ! :)

Great - and yes - you need to shift anything from the HTTP:: object into variables before you trigger any HTTP:: redirection/respond.

 

Basically, once you have used HTTP::redirect/respond (or the LTM policy equivalents), the entire HTTP:: object is invalidated, and cannot be accessed (apart from HTTP::has_responded)
