LTM 11.4.1 - Trying to Identify equivalent features to cisco ACE

Thanks. That was of real help. But looks like all the features i am looking for are available only in 11.5, reading through the link. I am still running 11.4.1, have opened a support case to see if they can suggest any similar option in 11.4.1, may be they will ask me to upgrade to 11.5. Also, the Transparent Proxy mode option in HTTP profile, in 11.5, seems to be the way to allow LTM to forward invalid HTTP traffic to the pool server, similar to the "parsing non-strict" option in Cisco ACE.
