Fix Varnish on Magento

I have a root server with Magento Community edition 1.7.0.2. It uses Memcached and APC to speed up the pages. Server is running Apache and nginx. Varnish is installed on the server to get full page caching in Magento using the Turpentine Varnish extension for Magento. However, It does not seem to work as it should. Your job will be: - to confirm that Varnish is configured correctly and is working well with Magento At the moment it is not working. Perhaps because of a non standard port setting on the server - to make sure Varnish works well and with no conflicts together with Memcached - to configure the system so that catalog updates are reflected on the front end - to (if needed) punch holes for modules that show random products in blocks and similar as well as shopping cart After you are finished we are checking that Varnish is working correctly by: 1. Verifying activity on varnishstat 2. Checking with Crome browser extension "Varnish Cache Efficiency". It should show that 100% of the request is served by Varnish. 3. Checking page load time for www.ovationmusic.com. Now it is around 6 seconds, it should be close to one second. A similar store is [login to view URL] This runs Varnish successfully and fills criteria 2-3 above. (I don't have access to that server to check nr 1) You will have full access to root server via ftp, WHM, c-panel and ssh
