Need assitance in applying URI based customized persistence profile through iRule

Hi Rajendra,

You can do both types of persistence on the same VS, but you will probably want to remove the persistence from the VS itself and rely on the IRULE to do all the persistence.

In the irule this is easy to do. You can isolate the persistence in the logic of the irule and tell the current connection to persist on JSESSIONID or on cookie persistence depending on the condition. Let me know if you need more help with getting this implemented. If you can paste the current irule/VS config you are working with, that could be helpful

Thanks Matt

This worked for only login and application login and logout session. But traffic related to any process done after logging to the application, used to load balance among the pool members and application breaks.

do all the uri after logging in start with /abc?

is it possible the request after logging in matches more than one condition in the irules?

have you tried tcpdump/ssldump to see what is going on exactly? you have private key to decrypt traffic, haven't you?

e.g.

 tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x or host y.y.y.y or host z.z.z.z -v

x.x.x.x is virtual server ip
y.y.y.y is pool member ip
z.z.z.z is another pool member ip

by the way, i think the rule1 should look like this.

when HTTP_REQUEST { 
  switch -glob [HTTP::uri] { 
    "/abc*" { 
      if { [HTTP::cookie exists "JSESSIONID"] } {
        persist uie [HTTP::cookie "JSESSIONID"] 300
      }
      pool pool_abcservers 
    }
  }
}
when HTTP_RESPONSE {
  if { [HTTP::cookie exists "JSESSIONID"] }  {
    persist add uie [HTTP::cookie "JSESSIONID"]
  }
}
