I have a virtual server standard+http which relies on an HTTP header for persistence. Only the very first HTTP request matter, I do not need HTTP parsing for the rest of the session. Unfortunatly the load is very high on this virtual server and I am looking for performance improvements. I cannot use fastL4+HTTP as the serverside connection is already setup when the first HTTP request comes in.
I found that BIGTCP::release_flow allows a FIX session to start in L7 mode and transition later to fastL4.
Can this command be used without FIX licence on a plain HTTP VIP ? ideally within an HTTP_REQUEST event.
other suggestions are also welcome
Unfortunately no, You have to acquire a special license when you want to use FIX over a fastl4 profile, Please refer to this guide for more information about FIX, and the features extended by the license.
Have a good day.
that is unfortuante. any other way to perform such a transition outside of the FIX use case ?
maybe with the 'virtual' irule command to switch to a fastL4 virtual server ? Though I don't know if the serverside TCP context would be carried over.
