Using F5 as a fall back host

Hello:     Is any using the F5 device itself as a fall back host? I would like to host the maintenance page on the device itself if possible instead of having another server as the fallback host...

SO this logic should work - based on the trimmed down version without the image (for easier following):

when RULE_INIT {
  set polr "We are currently performing maintenance.  Please check back later."
}
when HTTP_REQUEST {
  if {[active_members Wildcard_Pool_Test] == 0} {
    HTTP::respond 200 content $::polr
  }
  elseif {[HTTP::cookie exists "cookieName"]} { 
        HTTP::cookie decrypt "cookieName" "passphrase" 
      }   
} 
  when HTTP_RESPONSE { 
      if {[HTTP::cookie exists "cookieName"]} { 
         HTTP::cookie encrypt "cookieName" "passphrase" 
      } 
  }
