WP Super Cache WordPress Plugin overview

WP Super Cache Wordpress Plugin is used to A very fast caching engine for WordPress that produces static html files..

This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

The static html files will be served to the vast majority of your users, but because a user's details are displayed in the comment form after they leave a comment those requests are handled by the legacy caching engine. Static files are served to:

  • Users who are not logged in.
  • Users who have not left a comment on your blog.
  • Or users who have not viewed a password protected post.
  • 99% of your visitors will be served static html files. Those users who don't see the static files will still benefit because they will see different cached files that aren't quite as efficient but still better than uncached. This plugin will help your server cope with a front page appearance on digg.com or other social networking site.

    If for some reason "supercaching" doesn't work on your server then don't worry. Caching will still be performed, but every request will require loading the PHP engine. In normal circumstances this isn't bad at all. Visitors to your site will notice no slowdown or difference. Supercache really comes into it's own if your server is underpowered, or you're experiencing heavy traffic. Super Cached html files will be served more quickly than PHP generated cached files but in every day use, the difference isn't noticeable.

    The plugin serves cached files in 3 ways (ranked by speed):

  • Mod_Rewrite. The fastest method is by using Apache mod_rewrite (or whatever similar module your web server supports) to serve "supercached" static html files. This completely bypasses PHP and is extremely quick. If your server is hit by a deluge of traffic it is more likely to cope as the requests are "lighter". This does require the Apache mod_rewrite module (which is probably installed if you have custom permalinks) and a modification of your .htaccess file. Visits by anonymous or unknown users will be served this way.
  • PHP. Supercached static files can now be served by PHP. The plugin will serve a "supercached" file if it exists and it's almost as fast as the mod_rewrite method. It's easier to configure as the .htaccess file doesn't need to be changed. You still need a custom permalink. You can keep portions of your page dynamic in this caching mode. Your server may not cope as well with a really large amount of traffic. (You're gaming Digg aren't you? You'll need mod_rewrite, the rest of us are ok with PHP!)
  • Legacy caching. This is mainly used to cache pages for known users. These are logged in users, visitors who leave comments or those who should be shown custom per-user data. It's the most flexible caching method but also the slowest. As each page is different it's often better not to cache pages for these users at all and avoid legacy caching. Legacy caching will also cache visits by unknown users if this caching mode is selected. You can have dynamic parts to your page in this mode too.
  • If you're new to caching use PHP caching. It's easy to set up and very fast. Avoid legacy caching if you can.

    Recommended Settings

    Advanced users will probably want to use mod_rewrite caching, but PHP caching is almost as good and recommended for everyone else. Enable the following:

  • PHP caching.
  • Compress pages.
  • Don't cache pages for known users.
  • Cache rebuild.
  • CDN support.
  • Extra homepage checks.
  • Garbage collection is the act of cleaning up cache files that are out of date and stale. There's no correct value for the expiry time but a good starting point is 1800 seconds if you're not using legacy mode. If you are using that mode start with an expiry time of 600 seconds.

    If you are not using legacy mode caching consider deleti How do I know my blog is being cached? Enable debugging in the plugin settings page and load the log file in a new browser tab. Then view your blog while logged in and logged out. You should see activity in the log. View the source of any page on your site. When a page is first created, you'll see the text "Dynamic page generated in XXXX seconds." and "Cached page generated by WP-Super-Cache on YYYY-MM-DD HH:MM:SS" at the end of the source code. On reload, a cached page will show the same timestamp so wait a few seconds before checking. In legacy caching mode, if you have compression enabled, the text "Compression = gzip" will be added. If compression is disabled and the page is served as a static html file, the text "super cache" will be added. The only other way to check if your cached file was served by PHP script or from the static cache is by looking at the HTTP headers. PHP cached pages will have the header "WP-Super-Cache: Served supercache file from PHP". Legacy cached files will have the header, "WP-Super-Cache: Served legacy cache file". I used the Live HTTP Headers extension for Firefox to examine the headers. You should also check your cache directory in wp-content/cache/supercache/hostname/ for static cache files. If the plugin rules are missing from your .htaccess file, the plugin will attempt to serve the super cached page if it's found. The header "WP-Super-Cache: Served supercache file from PHP" if this happens. Legacy (WP-Cache) vs Supercache files WP-Cache files are stored in wp-content/cache/ (or on MU sites in a blogs sub directory) and are named wp-cache-XXXXXXXXXXXXXXXXX.html. Associated meta files are stored in a meta sub directory. Those files contain information about the cached file. These files are generated by the "legacy caching" code in the plugin. Supercache files are stored in wp-content/cache/supercache/HOSTNAME/ where HOSTNAME is your domain name. The files are stored in directories matching your site's permalink structure. Why is WP-Super-Cache better than WP-Cache? This plugin is based on the excellent WP-Cache plugin. Besides the caching WP-Cache did this plugin creates copies of every page that is accessed on a blog in a form that is quickly served by the web server. It's almost as quick as if the you had saved a html page in your browser and uploaded it to replace your homepage. Will comments and other dynamic parts of my blog update immediately? Comments will show as soon as they are moderated, depending on the comment policy of the blog owner. Other dynamic elements on a page may not update unless they are written in Javascript, Flash, Java or another client side browser language. The plugin really produces static html pages. No PHP is executed when those pages are served. "Popularity Contest" is one such plugin that will not work. Will the Super Cache compression slow down my server? No, it will do the opposite. Super Cache files are compressed and stored that way so the heavy compression is done only once. These files are generally much smaller and are sent to a visitor's browser much more quickly than uncompressed html. As a result, your server spends less time talking over the network which saves CPU time and bandwidth, and can also serve the next request much more quickly. How do I make certain parts of the page stay dynamic? Note: this functionality is disabled by default. You will have to enable it on the Advanced Settings page. There are 2 ways of doing this. You can use Javascript to draw the part of the page you want to keep dynamic. That's what Google Adsense and many widgets from external sites do and is the recommended way. Or you can use a WP Super Cache filter to do the job but you can't use mod_rewrite mode caching. You have to switch to PHP or legacy caching. WP Super Cache 1.4 introduced a cacheaction filter called wpsc_cachedata. The cached page to be displayed goes through this filter and allows modification of the page. If the page contains a placeholder tag the fi;
