Compressing php output with wp-cache2 WordPress Plugin

Angsuman Chakraborty

September 18th, 2005

Wp-Cache2 is a WordPress Plugin to cache WordPress generated pages. However it doesn't work with in-built gzip compression. Lets see how we can solve it.

Wp-Cache 2 significantly increases performance of WordPress enabled websites. Additionally it drastically reduces the processing load on the machine. It is intelligent to understand when to refresh the cache based on author / publisher activity.

This blog uses wp-cache 2.

It comes with some costs. It doesn't allow you to compress your output in gzip format, a facility provided by WordPress.

BTW: wp-cache-2 doesn't work on Windows based servers.

The solution is to use Apache mod_deflate module.

A simple configuration (add in httpd.conf) might be:

AddOutputFilterByType DEFLATE text/html text/plain text/xml application/x-httpd-php

This assumes you have mod_deflate loaded. If not load it first:

LoadModule deflate_module modules/mod_deflate.so

Let me know your experience with this.

It seems to me that the problem was that with WP’s gzip turned on, it was caching the zipped output. I edited wp-cache-phase1.php and put in the following:

if( extension_loaded('zlib') ) ob_start('ob_gzhandler');

right above this line:

foreach ($meta-»headers as $header) {

And it seems to work beautifully. That caches the plaintext, but gzips the text before delivering on cached hits. Might work for people you can’t mess with server configuration files.
