or modify your irule with the following code:

 

when HTTP_RESPONSE_DATA {
 
set find "<HEAD>"
set replace "<HEAD> SOME_OTHER_DATA"
 
if {[ regsub -all $find [HTTP::payload] $replace new_response] > 0} {

	log "Replacing payload with new data."
	HTTP::payload replace 0 [HTTP::payload length] $newdata
	HTTP::release
}
 
}

regards
