Hi, You don't need disable cookies, you could "pass" requests with specific cookies (wordpress_logged_in and others) In the other hand, you need a wordpres plugin in order to purge new comments, posts, etc. Check this one (includes VCL example): http://wordpress.org/extend/plugins/cd34-varnish-esi/ There is several plugins doing the job, take a look on them. Hope this helps. Kind regards. _______________________________________________ varnish-misc mailing list [email protected] https://www.varnish-cache.org/lists/mailman/listinfo/varnish-misc
