HTTP::collect and HTTP::payload corrupt?

I have since modified the HTTP_RESPONSE_DATA to look inside the payload:

 

 

when HTTP_RESPONSE_DATA {

 

if { $debug>=3 } { log local0.info "HTTP_RESPONSE_DATA triggered for castoruri $castoruri" }

 

set payload [HTTP::payload]

 

 

binary scan [HTTP::payload] H* payload_hex

 

This POSTs back through the iRule like a client request, and so the iRule will trigger HTTP_REQUEST again

 

if { $debug>=3 } {log local0.info "REQUEST IS POST $original_path HTTP/1.1\r\nHost: $original_castordomain\r\nContent-Length: $contentlength\r\n\r\n$payload" }

 

HTTP::retry "POST $original_path HTTP/1.1\r\nHost: $original_castordomain\r\nX-Forwarded-Host: $original_castordomain\r\nContent-Length: $contentlength\r\n\r\n$payload\r\n"

 

HTTP::respond 200 content "

 

$payload_hex

 

"

 

 

 

}

 

 

I have compared the output in my browser with the hex dump of the original file and they are identical, which is a good sign! So it must be something to do with the POST request that is corrupting it..hmm
