Hi, it is a good question despite the wiki documentation. The closest I got to success was:

when HTTP_RESPONSE {
    HTTP::respond 404 -version 1.1 -reset 
}

I could see big-ip sending RST to the server, but it was needed to remove "noserver" statement. You may need to empty the "Server Agent Name" option to the HTTP profile to have the same effect.

Regards.
