WP Super Cache 1.0 will be out soon(ish) but I need testers to bang on the development version available on the download page.
This version should be significantly faster if you have a lot of mobile visitors, plus it adds support for https secure pages. The speed came about by saving those files as static files in the supercache directories rather than the old “legacy caching” of WP Cache. You’ll see files like index-mobile.html(.gz) and index-https.html(.gz) in those directories. Be aware that if you use a flat permalink structure the plugin opens the root supercache directory for reading to find the index* files. This may or may not be an issue with directories containing a very large number of directories (10,000+ for example).
HTTPS support is built into the mod_rewrite rules so those files are served by the web server directly, but PHP serves the mobile clients. Only now you’ll be able to cache many times more mobile pages than before. There’s negligible speed difference between PHP and mod_rewrite modes anyway in normal operation.
There’s also a handy little “donotcachepage” GET parameter now. Add that, giving it the value of a secret key from the Advanced settings page and the current page will not be cached in any way.
There is lots of new code in the plugin. It’s running fine here, and a few other people have had no problems but I need more feedback. If you have a development server please give this a go, and if it works ok I believe it’s good enough to go live, under supervision. Don’t go install it on a Friday afternoon…
With the upgrade to WordPress 3.2 I moved this site and my photoblog to a Multisite install so I’ve been looking at making Supercache work better in that environment too.
I also installed Varnish as a front end cache and woah, I’m impressed. Setup was fairly easy though it’s still not 100% right. When I make posts the following page is a blank page except for the blog title, and when I (as a logged in user) leave a comment I get a 500 error and wp-comments-post.php doesn’t redirect. I’m still trying to debug those issues. I mentioned this on Google Plus a few days ago but expect a follow up post on Varnish with docs in the near future.
Now all I need is traffic. I should blog more!
