nested elseif unexpected behaviour

So are you saying that in the absence of the maintenance condition it all works?

 

when HTTP_REQUEST {
    if { [class match [string tolower [HTTP::uri]] starts_with QA-HEC-ENT-URI] } {
        pool INF-ENT-HTTP
    } elseif { [class match [string tolower [HTTP::uri]] starts_with QA-HEC-URI] } {
        pool INF-HEC-DNNREDIRECT
    } else { 
        pool INF-HEC-HTTP
    }
}

Are you specifically testing the maintenance condition, or are you saying that the inclusion of the maintenance condition code causes issues when not in a maintenance condition ([active_members INF-HEC-HTTP] < 1)?

 

If the former, perhaps removing the default HTTP::uri / statement might help. You're basically saying that for anything that doesn't end with .gif or .css, rewrite the URI to /.

 

Otherwise, as alluded earlier, it may be a good idea to fire up a client side analysis tool like Fiddler or HTTPWatch to see what's going on under the hood.
