3rd Party Plugin Compatibility: AMP

[raamdev]

The AMP plugin adds support for the Accelerated Mobile Pages (AMP) Project. AMP is already used by Google and is becoming a big thing. The AMP WordPress plugin (developed by Automattic) already has 10k+ active installs.

Initial testing with Comet Cache v160223.1 indicates that AMP pages (which are generated by appending /amp/ to the URL, e.g., for /example-post/ you simply access /example-post/amp/ to get the AMP version) are cached fine by Comet Cache, resulting in a cache file stored in [...]/example-post/amp.html.

However, what is not working is the automatic clearing of the AMP cache file when the post changes. So if we edit the Example Post, Comet Cache clears the cache file for /example-post/ but does not clear the cache file for /example-post/amp/. We need to update Comet Cache to add support for the AMP plugin.

This is an easy fix. We can change this line to the following:

return '(?:\/index|\/amp)?(?:\.|\/(?:page\/[0-9]+|comment\-page\-[0-9]+)[.\/])';

The same thing in this line also.

We may also need to look at how permalinks are structured when this plugin is running, because we need to know if pagination occurs like /amp/page-2 or /page-2/amp for instance.

It appears that Comments, Pages, and Archives are not supported at all yet by the AMP plugin. The comments section and any links to comments do not appear on posts that are loaded via AMP.

The only other thing to note is that you can also load the AMP version of a post by appending ?amp=1, so we should be sure to consider that.

@jaswsinc FYI, I tested and confirmed the fix you noted above. It works great! Cache files for AMP versions of posts are now automatically cleared when a post cache needs to be cleared. :-) I've submitted a PR that I will be merging soon.

Cool. That's awesome!

Next Release Changelog:

AMP-generated pages will be cached and those cache files will be intelligently cleared when necessary to keep things up-to-date. See Issue #688.
