Migrating from Varnish

[Andrei]

Hi all,

I've been using Varnish for 4 years now, but quite frankly I'm tired of
using it for HTTP traffic and Nginx for SSL offloading when Nginx can just
handle it all. One of the main issues I'm running into with the transition
is related to cache purging, and setting custom expiry TTL's per
zone/domain. My questions are:

- Does anyone have any recent working documentation on supported
modules/Lua scripts which can achieve wildcard purges as well as specific
URL purges?

- How should I go about defining custom cache TTL's for: frontpage,
dynamic, and static content requests? Currently I have Varnish configured
to set the ttl's based on request headers which are added in the config
with regex matches against the host being accessed.

Any other caveats or suggestions I should possibly know of?
