Dear All After a lot of struggle I have been able to install Varnish and Memcache.
Timebeing Memcache I have disabled (actually could not realize if it made any difference in page loading for authenticated users, will take it up after done with Varnish configuration improvements).
With Varnish my observations are
1. It works great. 2. But sometimes, it behaves crazy. It gives cached pages to authenticated users.
Is there any rule I can put in VCL file, where it will mandate that the logged in users should not be given cached pages. If this can not be achieved then probably I would not be able to use Varnish. I am sure there must be a way out.
I have used both the VCL files given in links below, and my observation is same.
1. VCL sample from lullaboat http://www.lullabot.com/sites/lullabot.com/files/default_varnish3.vcl_.txt
2. VCL sample from four kitchens https://fourkitchens.atlassian.net/wiki/display/TECH/Configure+Varnish+3+for...
