Can't get HTTP payload modification iRule to work

Hey Kirk --

I've had good success collecting as much data as necessary, then using regsub against the collected data instead of having to calculate insertion points:

set payload [HTTP::payload]
set find "/intl/en_com/images/logo_plain.png"
set replace "http://kaybee.org:8080/google_f5.png"
regsub $find $payload $replace payload
HTTP::payload replace 0 [HTTP::payload length] $payload

In either case, though, if the content length is changing, you'll need to set the Response Chunking option in your http profile to "Re-Chunk" so LTM doesn't send out an incorrect Content-Length header(which can cause the browser to hang or otherwise act funky)
