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):

There is several plugins doing the job, take a look on them.

Hope this helps.
Kind regards.
