Hi,
I am very close to rolling out an upgrade to a site using installer/ buildout from an older version and need a bit of help on configuring my environment.
Currently, the site has 4 zope clients with one zeo server and is fronted by Apache. It is running on a OSX server.
The clients run on ports 8081,8082,8082 & 8084
The relevant portions in httpd.conf Apache config file (that seem to be specific to my setup) are:
====================
<Proxy Balancer://lb>
BalancerMember
http://127.0.0.1:8081 BalancerMember
http://127.0.0.1:8082 BalancerMember
http://127.0.0.1:8083 BalancerMember
http://127.0.0.1:8084</Proxy>

=========================
From this I'm surmising that Apache is handling load balancing across my clients and also the rewrite rules so my Varnish would, I guess, be behind(?) Apache
However, with this installation, I would like to also install Varnish using the recipe at :
http://pypi.python.org/pypi/plone.recipe.varnishI will be running the upgraded site on ports 8091,8092,8093 & 8094 (Zeo address on 8101) which, obviously I will be configuring in my buildout.
Am I right in thinking that I once I have amended my Apache Load Balancing ports appropriately (to 8091,8092,8093 & 8094) , I need to amend my varnish recipe to read thus:
[varnish-instance]
backends =
/VirtualHostBase/http/intranet:80/BTX:127.0.0.1:8000
Start Varnish and set up CacheFu with my caching policies?
...or have I misunderstood? (This is all alien territory for me, as you may have already grasped!)
