Hi,

We are starting the implementation phase of a sizable custom social 
networking project and find the Stripes Framework thus far extremely 
appealing for someone that has been architecting and developing Java 
applications since Java's early days... i.e. someone that may be 
considered old school :-)

We will have a total of total of 8 application servers (GlassFish 3.0) 
s/w load balanced over 4 virtualized containers (Solaris 10 zones) on 2 
servers.  Due to 24-7 usage (yes the system will be accessed in 4 
continents), rolling upgrade requirements, using a s/w vs. h/w load 
balancer, etc... we had to re-think the luxury of having "stickiness".  
Not to mention that "stickiness" has other less subtle issues like being 
at odds with HTTP 1.1 keep-alives and eventually one realizes they 
simply have to disable keep-alives and lose the performance benefits it 
affords.  All this to say that "sticky sessions" like any solution has 
both Pro's and Con's and that is not something I want to debate.

With that said one area we would like to handle differently going 
forward is NOT utilize "server affinity" aka "sticky sessions".  We are 
planning on using cookies (with security measures for tampering, etc.) 
to persist data objects stored on the ActionBeanContext.

Q1.:  Has anyone utilized Stripes in this way?

Q2.:  Any thoughts / considerations / gotchas on NOT using "sticky 
sessions" with Stripes?

Q3.:  Besides the objects that we write to the ActionBeanContext are 
there any other things in the Stripes framework that we need to be aware 
of that we need to persist somehow?

Q4.:  Any structures that Stripes persists on a user "session" (I doubt 
there are any but ya never know)?

BTW we are looking at Stripes 1.5.3 with JPA + Hibernate + Spring + 
Lucene + etc...

Thank You,

--Nikolaos
