The reasoning behind this is so joomla can reduce the risk of session hijacking and whatnot , which makes sense ( I guess).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The problem is varnish is having a very very difficult time knowing when to pipe or pass the traffic to the backend webserver if a logged in session happens. It seems that unless you patch joomla to do its own internal checks and determine if a user is anonymous or not, and send a custom http header that varnish can read, there is no other real way to make varnish work with joomla.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’d be really appreciative if anyone can share their relevant VCL if they have in fact achieved a working relationship between varnish (I’m running 2.1) and joomla 1.5.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks in advance,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Kevin<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
