http_request payload logging is not full

Hi Ravi,

The HTTP_RESPOND event is triggered once TMM has collected enough packets to get the last HTTP header. If you call [HTTP::payload] in HTTP_RESPONSE, it will only return the HTTP payload available in the packet(s) required to parse all of the HTTP headers. If you want to collect the full HTTP payload, you'll need to use HTTP::collect:

 http://devcentral.f5.com/wiki/default.aspx/iRules/http__collect
when HTTP_RESPONSE {

   Trigger collection for up to 1MB of data
  if {[HTTP::header exists "Content-Length"] && [HTTP::header "Content-Length"] <= 1048576}{
    set content_length [HTTP::header "Content-Length"]
  } else {
      set content_length 1048576
  }
   Check if $content_length has been set and is not set to 0
  if { $content_length > 0} {
    HTTP::collect $content_length
  }
}
when HTTP_RESPONSE_DATA {
   do stuff with the payload
  set payload [HTTP::payload]
}
