Change persistence per pool

Hi

 

We have no default persistence as that has caused polarisation of servers due to NAT rules further up the stream, however I need to apply source_ip affinity on one pool. my irule is as follows,

 

when HTTP_REQUEST { if {[HTTP::host] eq "someurl.com"} {pool somepool}

 

as you can see I am switching on host header, is there any way of making that pool use source affinity or is this set globally per Virtual Server?

 

Any help would be greatly appreciated, I have tried putting persistence in before and inbetween the pool but to no avail.

    Try something like this..

    when HTTP_REQUEST {
    if {[string tolower [HTTP::host]] equals "someurl.com"}{
    persist source_addr
    } else{
      return
    }   
}
