Re: Varnish

[William Bell]

OK.

Here is the answer for us. Here is a sample default.vcl. We are validating
the LastModified ( if (!beresp.http.last-modified) )
is changing when the core is indexed and the version changes of the index.

This does 10 minutes caching and a 1hr grace period (if solr is down, it
will deliver results up to 1 hr).

This uses the URL for caching.

You can also do:

http://localhost?PURGEME

To clear varnish if your IP is in the ACL list.
