The problem is our business require traffic to be end to end encrypted for that I am using performanceL4 and after that I am not able to host maintenence page on f5 using iFiles as if I use http profile with perfomanceL4 then it breaks the connection. Is there a way that can be used to host a maintenence page on f5 using iFile.
may this be usable?

this is sorry page
Thanks, I see you used when HTTP_REQUEST event in your iRule. The problem is if use this event, than I must have to use HTTP profile with VS which will intern not trigger maintenance page without doing ssl bridging.
The second option I can utilize is hosting maintenance page on an external server and route traffic to that server in case the VS goes down. Not sure if it is possible without SSL bridging.?
