i'm intrigued by your LB-method logic - [$::Counter1 % $cc]

i have a similar iRule in which i use LB::select in HTTP_REQUEST to select a member from a pool and compose my redirect with that result:

if { [active_members [LB::server pool]] == 0 } {
    HTTP::respond 404 "No servers" noserver
} else {
    set sel_mem [LB::select]
    HTTP::redirect "http://[getfield $sel_mem " " 4]:[getfield $sel_mem " " 5][HTTP::uri]"
