iRules HTTP_RESPONSE based on Pool?

Hi Tony: would it be possible to simply set a variable in your HTTP_REQUEST event that you reference on HTTP_RESPONSE? For example, you've already made a decision to send some traffic to one pool or the other based on uri, so you should be able to do this.

 

 

Here's some non-tested, free form code as an example.

 

when HTTP_REQUEST {
  if {HTTP::uri equals '/foo'} {
    set selected 'gopher'
    pool gopher
    }  else { 
    set selected 'http'
    pool http
    }
}
when HTTP_RESPONSE {
  log local0. "This response is coming from pool $selected..."
}

 

I'm sure I've got a fat-finger or two in here but hopefully it'll give you an idea of what I am thinking here.
