Hi,
I start using Varnish on Apache HTTPD, everything is working perfectly, except login components, I apply this setting:
snipt.net/fevangelou/the-perfect-varnish-configuration-for-joomla-websites/
and the problem is user cannot login via K2 original User Module or joomla login default page. sometimes people would login but they would see someone else's profile.
looking forward to any suggestion or even clue to get rid of this.
