Compress if RTT is above a certain amount

I'm trying to use the following iRule: when HTTP_REQUEST { set rtt [TCP::rtt] } when HTTP_RESPONSE { if {$rtt < 1600 } { log "NOcompress rtt=[TCP::rtt]" COMPRESS::disable } ...

You are comparing on a stored value from the request, but logging the current value from the response. You could log both values to see if they are different:


when HTTP_REQUEST {
  set rtt [TCP::rtt]
}
when HTTP_RESPONSE {
   if {$rtt < 1600 } {
      log "NOcompress rtt=[TCP::rtt], stored rtt=$rtt"
      COMPRESS::disable
   }
   elseif {$rtt > 1600 } {
      log "compress current rtt=[TCP::rtt], stored rtt=$rtt"
      COMPRESS::enable
      COMPRESS::gzip level 9
   }
}
