Irule persist lookup source_addr for specific virtual server

Marvin,

For the most part, getting an added command to look across other virtuals persist records without enabling persist across * is slim. There are probably too many dark corners around which that could / would break. The preferred mechanism to do this would be with the table commands.

A minimal framework using the table commands could look similar to this:

when RULE_INIT {
     probably makes more sense to use data groups here
     quick and dirty PoC
    set static::web1_peer "/Common/vs_web2"
    set static::web2_peer "/Common/vs_web1"
}

when LB_SELECTED {
  table set [virtual name]:[IP::client_addr] [LB::server]
}

when HTTP_REQUEST {
    if { [virtual] eq "/Common/vs_web1" } {
        set peer ${static::web1_peer}
    }
    elseif { [virtual] eq "/Common/vs_web2" } {
        set peer ${static::web2_peer}
    }
    set peer_persist [table lookup ${peer}:[IP::client_addr]]
    if { ${peer_persist} ne "" } {
        log local0. "${peer} persist-record: ${peer_persist}. Select and persist to partner memeber."
    }
    else {
        log local0. "Peer persist-record not found.  Making selection."
    }

}
