Ok,

the issue is because you stripped one part of the irule. if the irule use only query parameter, you can remove the 

if {[string length $msisdn] } {
... I answered this issue previously before you remove the XML part by adding a else statement 
} else { pool $default_pool member 172.24.248.85 8080 }
.

The irule become:

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

when HTTP_REQUEST {
    set msisdn [URI::decode [URI::query [HTTP::uri] msisdn]]
        switch -glob $msisdn {
            "*0" {
                if { [LB::status pool $default_pool member 172.24.248.85 8080] eq "up" } {
                    pool $default_pool member 172.24.248.85  8080
                } else {
                    pool $default_pool member 172.24.248.85  8180
                }
            }
            "*1" {
                if { [LB::status pool $default_pool member 172.24.248.85 8180] eq "up" } {

            default { pool $default_pool member 172.24.248.85 8080 }

But you can look at my previous irule assigning a list of pool members and not only 2...
