Great, so first step is to turn it off at the server. If you can't do that, try this simple iRule to remove it from responses:

when HTTP_RESPONSE {    
    if { [HTTP::header exists "Strict-Transport-Security" } {        
        HTTP::header remove "Strict-Transport-Security"
    }
}

If that does the trick, then you just need to wait that 500 seconds for the cache to timeout and then try again.
