WP Super Cache is a plugin for WordPress that creates cached copies of your blog posts and pages, making your site much faster to serve. It’s also ideal for coping with sudden surges of traffic.
I released a new version of the plugin this morning. This is a bugfix release:
- Mike Beggs contributed a number of changes:
- Better support for Win32 NTFS
- Better use of the “Vary” header so proxy servers won’t cache the wrong page. If you see leakage of comment details on posts this will fix that problem.
- WP-Cron handles cleanup of expired cache files in the background now.
- Disable mod_deflate if it’s running as it sometimes tries to compress gzipped files. Remove wp-content/cache/.htaccess for that file to be updated.
- Lazy and Otto both recommended using get_comment() instead of the depreciated get_commentdata()
- A basic “uninstall” function has been added to remove some of the files the plugin creates. It’s called when you deactivate the plugin.
- PHP running as a CGI doesn’t support apache_request_headers() so that’s been added too.
- And I almost forgot, the admin page received a slight makeover.
Get the plugin from the download page!

Ramoonus – check the readme.txt, this is in the troubleshooting section.

Does this make it any faster than before?

Oaky – nope, just fixes the above bugs.

Anyone done a GoDaddy check on the update to see if it works there yet?
Donncha (1707 comments.) on August 21, 2008 at 1:21 pm.
Steve – it’s worked on GoDaddy for ages. I fixed that problem in May.
George – best place to work through any installation problems is the forum on the download page. You’ll have to explain in more detail how it doesn’t work.
bcarter – there are plenty of ways!

Finally i said to myself “i am going to get this plugin to properly work” and i did, and it works brilliantly so i thank you!! One thing i would like to ask though is…the plugin is based on the old wp-cache plugin, you took it, pumped it with a valium and this came out. So is it working exactly like wp-cache does, caching your site, and super cache…is it crawling the site caching everything as html files?
There are a few ways to speed up your site, this is one i found was the best, using the caching that wordpress already has coded in : enter this into your config.php and i got a considerable speed difference.
// Enable the WordPress Object Cache:define('ENABLE_CACHE, true');
Donncha (1707 comments.) on August 21, 2008 at 8:39 pm.
Neil – the plugin only caches pages that are visited. Caching pages that nobody visits doesn’t make sense!
Good tip on the ENABLE_CACHE, but the apostrophes are in the wrong place, should be:
define( ‘ENABLE_CACHE’, true );
You should also download and install one of the object cache plugins to take advantage of that caching. Google will find them!

Wow , it works just like Nitro !
tank you for very useful plug-in
Keep Up The Good Work

Funny about the apostrophes, dougal has left them out all together and written a nice post on how to use object cache within wordpress.

@Donncha
Ouch! I’m not sure that 3 months counts as “ages”.
I’ll try it out again this week (last attempt was probably 10 months ago).
@Neil
Isn’t valium a sedative?
