Varnish Full-Page Cache Is Now Configurable From the Opensolr Control Panel
Varnish full-page cache is now fully configurable from the control panel. The Varnish card in your server’s Services tab has a new Configure button.
01 Two ways to edit
Most of what people need from Varnish is a list of pages that must never be cached — shopping carts, product compare, anything that differs per visitor. You can now add those cache-exclusion rules directly, with a built-in URL tester to check a rule matches what you think it matches, and a one-click purge of the pages a rule covers.
If you would rather work at the level Varnish itself works at, you can edit the raw VCL in the same place.
02 A typo cannot take your site down
Every save is backed up, compile-tested and applied with zero downtime. A mistake in the configuration is caught before it is applied, so it can neither take your site down nor throw away a warm cache.
