Jitify for Apache, also known as mod_jitify, is a plug-in module for the Apache 2.2 web server. It performs transformations on outbound content. It works with both static content (flat files in the Apache docroot) and dynamic content (PHP, mod_proxy, etc).

Jitify for Apache currently supports HTML, JavaScript, and CSS2 content. On requests for other content-types, it leaves the HTTP response body unmodified.

1. If you don't already have an installation of Apache 2.2.x, download and install it. Make sure to enable mod_so for dynamic shared object support.
2. Download the jitify-core source distribution
3. Unpack the tar file:

           
   bunzip2 < jitify-core-version.tar.bz2 | tar xf -
   cd jitify-core-version
         

4. Edit the Makefile: set the $APACHE_HOME variable at the top to point to the base of your Apache installation.
5. Compile:

           
   make apache
         

6. When the compilation completes, the file mod_jitify.so will be in the build subdirectory. Copy it into the modules subdirectory under your Apache installation.
7. Add these lines to your httpd.conf:

           
   LoadModule jitify_module modules/mod_jitify.so
   <IfModule jitify_module>
       # Enable the minification transform
       Minify On
   </IfModule>
   
         

8. Stop and restart Apache.

Directives for use in httpd.conf:

• Minify On|Off

  Turn minification on or off.

  This directive may be used at the top level in httpd.conf and within <Location> and <Directory> blocks

mod_jitify uses the standard Apache logging mechanism to write diagnostic information to the httpd error log file (normally logs/error_log). The amount of information logged depends on the LogLevel setting:

• warn or higher: details of any syntax errors encountered while parsing content
• info or higher: measurements of processing speed and before-and-after content size for each request
• debug or higher: quite a bit of information about what the mod_jitify internals are doing
