Persistent State Store and eXist

Hank Ratzesberger
Greetings,

The blog mentioned work on a persistent store for the xforms state
that uses the embedded eXist db :

http://www.orbeon.com/blog/2007/10/29/a-disk-based-xforms-state-store- 
for-orbeon-forms/

I know I will find this out as soon as I upgrade, but I wonder
if this affects things if you deploy eXist separately and alongside  
Orbeon Forms.

http://mydomain.com/ - handled by Orbeon
http://mydomain.com/exist/rest/db - handled by exist

also if Apache is a front end, and proxying:

RewriteRule  ^/exist/rest/db(.*)   http://db.mydomain.com/exist/rest/ 
db$1 [P]

I'll be back from a trip in a week to give it a try.

P.S. I will be working with some seismologists to create a 3D model of
canyon that has been filled in with processed human waste, but we
call it fun with science.

It shouldn't, because the two databases will be in two different
webapps. They should remain independent.

This shouldn't be an issue either, because Orbeon accesses eXist in
embedded mode for the purpose of XForms state management. This means
that the communication doesn't go through HTTP.

Cool, please let us know if things run fine or not.
