LTM 11.4.1 - Trying to Identify equivalent features to cisco ACE

i upgraded to 11.5.1, and tried to enable http transparent proxy mode (using http-transparent profile) to a Virtual server that already has other profiles (SSL client, OneConnect, http-compression). But i get the following error, 01070734:3: Configuration error: In Virtual Server (/oracle/prod_443) HTTP is configured as a Transparent Proxy, and thus is incompatible with any other filter other than PEM. Looks like i cannot use this Transparent proxy mode in my configuration. Primarily i am looking for an equivalent to parising non-strict in Cisco. Anyone has an idea? i opened a support case and the engineer said this feature cannot be used with the VS config i have and suggessted to use iRule to implement the same. Is there a possible way to enable this using an iRule?
