Comet Cache
By WebSharks, Inc.

Description
If you care about the speed of your site, Comet Cache is one of those plugins that you absolutely MUST have installed 🙂 Comet Cache takes a real-time snapshot (building a cache) of every Page, Post, Category, Link, etc. These snapshots are then stored (cached) intuitively, so they can be referenced later, in order to save all of that processing time that has been dragging your site down and costing you money.

Comet Cache

Comet Cache

The Comet Cache plugin uses configuration options that you select from the options panel. See: Comet Cache -› Options in your Dashboard. Once a file has been cached, Comet Cache uses advanced techniques that allow it to recognize when it should and should not serve a cached version of the file. By default, Comet Cache does not serve cached pages to users who are logged in, or to users who have left comments recently. Comet Cache also excludes administrative pages, login pages, POST/PUT/DELETE/GET(w/ query string) requests and/or CLI processes.

FURTHER DETAILS

SO WHY DOES WORDPRESS NEED TO BE CACHED?

To understand how Comet Cache works, first you have to understand what a cached file is, and why it is absolutely necessary for your site and every visitor that comes to it. WordPress (by its very definition) is a database-driven publishing platform. That means you have all these great tools on the back-end of your site to work with, but it also means that every time a Post/Page/Category is accessed on your site, dozens of connections to the database have to be made, and literally thousands of PHP routines run in harmony behind-the-scenes to make everything jive. The problem is, for every request that a browser sends to your site, all of these routines and connections have to be made (yes, every single time). Geesh, what a waste of processing power, memory, and other system resources. After all, most of the content on your site remains the same for at least a few minutes at a time. If you’ve been using WordPress for very long, you’ve probably noticed that (on average) your site does not load up as fast as other sites on the web. Now you know why!

THE DEFINITION OF A CACHED FILE (FROM THE WIKIPEDIA)

In computer science, a cache (pronounced /kash/) is a collection of data duplicating original values stored elsewhere or computed earlier, where the original data is expensive to fetch (owing to longer access time) or to compute, compared to the cost of reading the cache. In other words, a cache is a temporary storage area where frequently accessed data can be stored for rapid access. Once the data is stored in the cache, it can be used in the future by accessing the cached copy rather than re-fetching or recomputing the original data.

PREPARE TO BE AMAZED / IT’S TIME TO SPEED THINGS UP

Comet Cache is extremely reliable, because it runs completely in PHP code, and does not hand important decisions off to the mod_rewrite engine or browser cache; also making Comet Cache MUCH easier to setup and configure.

In addition, Comet Cache actually sends a no-cache header (yes, a no-cache header); which allows it to remain in control at all times. It might seem weird that a caching plugin would send a no-cache header :-). Well, no-cache headers are a key component in this plugin, and they will NOT affect performance negatively. On the contrary, this is how the system can accurately serve cache files to public users vs. users who are logged-in, commenters, etc.

If you care about the speed of your site, Comet Cache is one of those plugins that you absolutely MUST have installed 🙂 Comet Cache takes a real-time snapshot (building a cache) of every Page, Post, Category, Link, etc. These snapshots are then stored (cached) intuitively, so they can be referenced later, in order to save all of that processing time that has been dragging your site down and costing you money.

The Comet Cache plugin uses configuration options that you select from the options panel. See: Comet Cache -› Options in your Dashboard. Once a file has been cached, Comet Cache uses advanced techniques that allow it to recognize when it should and should not serve a cached version of the file. By default, Comet Cache does not serve cached pages to users who are logged in, or to users who have left comments recently. Comet Cache also excludes administrative pages, login pages, POST/PUT/DELETE/GET(w/ query string) requests and/or CLI processes.

RUNNING COMET CACHE ON A WORDPRESS® MULTISITE INSTALLATION

WordPress Multisite Networking is a special consideration in WordPress. If Comet Cache is installed under a Multisite Network installation, it will be enabled for ALL blogs the same way. The centralized config options for Comet Cache, can only be modified by a Super Administrator operating on the main site. Comet Cache has internal processing routines that prevent configuration changes, including menu displays; for anyone other than a Super Administrator operating on the main site.

HOW TO ENABLE GZIP COMPRESSION FOR EVEN GREATER SPEEDS

You don’t have to use an .htaccess file to enjoy the performance enhancements provided by this plugin; caching is handled by WordPress/PHP alone. That being said, if you want to take advantage of GZIP compression (and we do recommend this), then you WILL need an .htaccess file to accomplish that part. This plugin fully supports GZIP compression on its output. However, it does not handle GZIP compression directly. We purposely left GZIP compression out of this plugin, because GZIP compression is something that should really be enabled at the Apache level or inside your php.ini file. GZIP compression can be used for things like JavaScript and CSS files as well, so why bother turning it on for only WordPress-generated pages when you can enable GZIP at the server level and cover all the bases!

If you want to enable GZIP and your site is running on the Apache web server, visit Dashboard -> Comet Cache -> Apache Optimizations -> Enable GZIP Compression?; or to enable GZIP compression manually create an .htaccess file in your WordPress® installation directory (or edit the one that’s already there) and put the following few lines in it. That is all there is to it. GZIP is now enabled!

<IfModule deflate_module>
<IfModule filter_module>
AddOutputFilterByType DEFLATE text/plain text/html
AddOutputFilterByType DEFLATE text/xml application/xml application/xhtml+xml application/xml-dtd
AddOutputFilterByType DEFLATE application/rdf+xml application/rss+xml application/atom+xml image/svg+xml
AddOutputFilterByType DEFLATE text/css text/javascript application/javascript application/x-javascript
AddOutputFilterByType DEFLATE font/otf font/opentype application/font-otf application/x-font-otf
AddOutputFilterByType DEFLATE font/ttf font/truetype application/font-ttf application/x-font-ttf
</IfModule>
</IfModule>
If your installation of Apache does not have mod_deflate installed. You can also enable GZIP compression using PHP configuration alone. In your php.ini file, you can simply add the following line anywhere: zlib.output_compression = on

EMERGENCY: IF ALL ELSE FAILS (HOW-TO REMOVE COMET CACHE)

Ordinarily you can just deactivate Comet Cache from the plugins menu in WordPress. However, if you’re having a more serious issue, please follow the instructions here.

Log into your site via FTP; perhaps using FileZilla.
Delete this file: /wp-content/advanced-cache.php
Delete this directory: /wp-content/plugins/comet-cache/
Remove this line from your /wp-config.php file: define(‘WP_CACHE’, TRUE);

Comet Cache is now completely uninstalled and you can start fresh 🙂

Very useful plugin
I have used this on sites where I do not want pretty permalinks.
Most caching plugins demand pretty permalinks, and this is not always an option.
So this plugin has helped a great deal for me, and got me to about 80% on google page load speed tests without using any other speed up plugins.

Jeeeeze that’s eas
Just installed Comet on another site – Currently using WP 4.94 but have been using Comet Cache on a few sites since it was first introduced as Zen cache. This because years ago (when Jason was still in the lower 48), I started using S2member, another great plugin also developed by WebSharks.

My anecdotal results say W3 might be a tiny bit better in terms of performance but it’s much deeper with a maze of settings so perhaps its just because you spend lots of time tweaking that it seems faster – kind of like a car runs better after its been washed. Either way, Comet easily gets you 99% there, seriously dramatic speed improvements and all you have to do is turn it on.

There is a lot to be said about real Plug&Play!!!

I neglected to note that there is actually one “tweak” that should be made by most users, anyone on a typical Linux hosting account which mostly are Apache servers. At the bottom of the settings page (Apache Optimization), turn on G-Zip. Even without it, performance increase is great but the compression can definitely help.

Just setup and forget
Install, enable the plugin and it does the rest. It has a clever feature which cleans the homepage (and other) cache(s) once there’s a new post or something is updated (such as settings, plugins or themes), keeping your site up to date.

New User
Activated and very impressed with easy setup. First impressions very good. Thanks for the plugin.

Perfect Cache plugin
I was using wp-rocket for my sites but was hating their plugin for compatibility with other geolocation based plugins, came across to comet cache pro through google and the plugin worked perfectly for all geoip based plugins, the developer saved me 500$ coz i was hiring a developer to accomplish my task. hats off to the developer!
