iRule to display site down irrespective of the state of pool members

Hi Raghav,

An easy way to do this would be to set a variable for comparison. In the below example, you would change the value of 'SiteDown' to 1 to manually enable the maintenance page. When set to 0, it would only redirect if there were less than 1 pool member available. Please let me know if you have further questions.

when HTTP_REQUEST {
Set SiteDown to 1 to enable maintenance page
set SiteDown 0
if {($SiteDown == 1) || ([active_members [LB::server pool]] < 1)}{
        HTTP::respond 503 content {.......}
        }
}
