In the irule, if the MSISDN is not in query string and content type is not XML, the member is not defined in the irule... the request is load balanced on on of pool members...

I added a else condition in the HTTP_REQUEST event.

when CLIENT_ACCEPTED { 
    set default_pool [LB::server pool]
}

HTTP_REQUEST {
    set msisdn [URI::decode [URI::query [HTTP::uri] msisdn]]
    if {[string length $msisdn] } {
        switch -glob $msisdn {
            "*0" {
                if { [LB::status pool $default_pool member 172.24.248.85 8580] eq "up" } {
                    pool $default_pool member 172.24.248.85  8580
                } else {
                    pool $default_pool member 172.24.248.85  8680
                }
            }
            "*1" {
                if { [LB::status pool $default_pool member 172.24.248.85 8680] eq "up" } {

            default { pool $default_pool member 172.24.248.85 8080 }
        }

        HTTP::collect [HTTP::header Content-Length]        
    } else { pool $default_pool member 172.24.248.85 8080 }
