Small experiment; Autoptimize with page cache

So I integrated a page cache (based on KeyCDN Cache Enabler) in Autoptimize, just to see how easy (or difficult) it would be. Turns out it was pretty easy, mostly because Cache Enabler (based on Cachify, which was very popular in Germany until the developer abandoned it) is well-written, simple and efficient. :-)

No plans to release this though. Or do you think I should?

Quick KeyCDN’s Cache Enabler test

cache enablerCache Enabler – WordPress Cache is a new page caching kid on the WordPress plugin block by the Switzerland-based KeyCDN. It’s based in part on Cachify (which has a strong user-base in Germany) but seems less complex/ flexible. What makes it unique though, is it that it allows one to serve pages with WEBP images (which are not supported by Safari, MS IE/ Edge or Firefox) instead of JPEG’s to browsers that support WEBP. To be able to do that, you’ll need to also install Optimus, an image optimization plugin that plugs into a freemium service by KeyCDN (you’ll need a premium account to convert to WEBP though).

I did some tests with Cache Enabler and it works great together with Autoptimize out of the box, especially after the latest release (1.1.0) which also hooks into AO’s autoptimize_action_cachepurged action to clear Cache Enabler’s cache if AO’s get purged (to avoid having pages in cache the refer to deleted autoptimized CSS/ JS-files).

Just not sure I agree with this text on the plugin’s settings page;

Avoid […] concatenation of your assets to benefit from parallelism of HTTP/2.

because based on previous tests by smarter people than me concatenation of assets can still make (a lot of) sense, even when on HTTP/2 :-)
