Hi Pedro,

I'm not positive on this, but I think you should be able to set a domain on the persistence cookie that would tell the client to present the cookie for any request to a subdomain on the domain you specify. This works when the node is setting the cookie, but I'm not certain it will work with a cookie the BIG-IP is setting itself.

Can you test it and report back? Note that you'll need to change the name of the cookie you're looking for, from my_persistence_cookie.


when HTTP_RESPONSE {
   if {[HTTP::cookie count] > 0 } {
      foreach aCookie [HTTP::cookie names] {
         if { $aCookie == "my_persistence_cookie" } {
            HTTP::cookie domain $aCookie mycompany.com
         }
      }
   }
}

[EDIT: fixed the setting of the domain on the cookie...and removed an extra pair of curly braces]
