You could prevent chunking on server responses (which will break the iRule as no content-length header is set) by setting the HTTP version in the request to 1.0: 


 Poached from http://devcentral.f5.com/wiki/default.aspx/iRules/CreditCardScrubber.html
when HTTP_REQUEST {

    Prevent the server from sending a compressed response
    remove the compression offerings from the client
   HTTP::header remove "Accept-Encoding"

    Don't allow response data to be chunked
   if { [HTTP::version] eq "1.1" } {

       Force downgrade to HTTP 1.0, but still allow keep-alive connections.
       Since HTTP 1.1 is keep-alive by default, and 1.0 isn't,
       we need make sure the headers reflect the keep-alive status.

       Check if this is a keep alive connection
      if { [HTTP::header is_keepalive] } {

          Replace the connection header value with "Keep-Alive"
         HTTP::header replace "Connection" "Keep-Alive"
      }

       Set server side request version to 1.0
       This forces the server to respond without chunking
      HTTP::version "1.0"
   }
}
