Hi, Enrico.<br>
<br>
I'm also installing Varnish here. But I'm facing a problem:
because of the cache, workplace logged in users cannot see their
modifications on jsp pages (offline projects).<br>
<br>
How did you deal with that? How Varnish can distinguish workplace
users requests (which cannot be cashed) from normal users requests
(which can be cashed) ?<br>
<div><br>
Thanks!<br>

Please consider that flex cache is cleaned for every publish event.
If you browse the list history (or google for it) you'll find that flex
cache cannot be informed of al the resources that change after a publish,
I.e. if you publish a template or an included jsp, all the cached resources
that are rendered with that jsp must be cleaned.
We worked around this by putting a varnish layer in front of opencms and
configuring jsps so that they return the "appropriate" cache directives.
Cheers,
Enrico
