title: Session data between servlets within a cluster
body: <p>So I'm not entirely certain how to word this question to ask it properly. I'll simply put down what I know of the situation, requirements, and ideas to paint the picture.</p>
  
  <p>I have two servlets: one is a grails 2.1.1 servlet and another is a Spring Webflow servlet. I've been tasked with inserting an iframe of the grails servlet into a page on the Spring Webflow servlet. The issue I of course raised was one of session data. The servlets are deployed to tomcat on the same server yet there are 3 servers in the cluster (all 3 servers have both servlets on them). Sticky sessions are enabled. My question is this: will I even be able share session data between the two servlets? I'd imagine that an iframe would produce a new jsession id for the grails app. If I can share data between the two servlets, how would that be accomplished? Using the typical getAttribute/setAttribute functions?</p>
  
  <p>Thanks for your thoughts!</p>
