iRule(event) evaluation

Hi,

JTI provides the right response. This answer is to help you to optimize the code.

when working with virtual server, there is more and more virtual server distributing request to different pools based on hostname or URI. If you apply your code to a such virtual server, every content will display the maintenance page if pool_fubar is unavailable.

this code is more generic and can manage per request maintenance pool detection.

when HTTP_REQUEST {
    if { [active_members [LB::server pool]] < 1 } { 
        HTTP::respond 200 content [ifile get sorry_file] "Content-Type" "text/html"
    }
}
