irule for load balance traffic based on query string

Hi,

this irule read the server in the query parameter and search it's IP in the static::web servers array

when RULE_INIT {
    array set static::webservers {
        1   1.1.1.1
        2   1.1.1.2
        3   1.1.1.3
    }
}

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

when HTTP_REQUEST {
    set target_member [URI::query [HTTP::uri] silo]
    if {!($target_member eq "") && [info exists static::webservers($target_member)} {
        pool $default_pool member $static::webservers($target_member)
    }
}
