## Description

CSS-JS-Booster is a PHP-script that tries to automate as many performance
 optimizing
steps related to CSS and JS embedding as possible. Depending on the amount of CSS,
CSS-images and JS, this can significantly increase loading speed of your site.

Note: Check by hand the htaccess-part! (see « Installation »)

#### For CSS optimization steps are:

 * combine multiple CSS-files resulting in less HTTP-requests
 * Optimize and minify CSS with CSSTidy
 * Embed any CSS-images smaller 24KB as data-URI or MHTML (for IE <= 7)
 * GZIP-compress the resulting CSS
 * Have browsers cache the result as long as it remains unchanged
 * If IE6: Issue a JS-command to fix background image caching behaviour

#### For JS optimization steps are:

 * Fetch JS from external servers and cache it locally
 * Combine multiple JS-files resulting in HTTP-requests going down
 * GZIP-compress the resulting JS
 * Have browsers cache the result as long as it remains unchanged

### Support

Please send bug reports this way: http://github.com/Schepp/CSS-JS-Booster/issues

When creating a new issue:

 * Make sure that you mention in the title that you are talking about the WordPress
   plugin (as there is a standalone version, too), e.g.: « [WP] Booster killed my
   site »
 * Make sure that you send me a link to your page
 * Tell me what exactly is broken
 * It helps if you put the HTML source code of your page resulting from activated
   Booster on http://pastebin.com/ and include a link to it
 * It helps if you put the HTML source code of your page resulting from deactivated
   Booster on http://pastebin.com/ and include a link to it
 * It helps if you tell me which plugins are active

## Installation

CSS-JS-Booster absolutely requires PHP 5. No PHP 4, sorry…
 Version-wise it is tested
up until PHP 5.3.

 * Copy the whole `booster`-folder into `wp-content/plugins/`
 * If not already there: create a subfolder named `booster_cache` inside `wp-content/`
   and CHMOD it to 0777 (give it write-permissions)
 * Go into the admin-panel to the plugins and activate `CSS-JS-Booster`
 * Check if the contents of the file `wp-content/plugins/booster/htaccess/.htaccess`
   were put into/appended to the .htaccess-file in the root of your WordPress-site.
   If not append them by hand.

#### Compatibility with other plugins

CSS-JS-Booster may in rare cases break some other plugins.
 I noticed for example
that plugins trying to calculate file-paths based on the src-attribute of the script-
tag break. So you need to check yourself.

If your site has many visitors, we suggest that you combine CSS-JS-Booster with 
WP-Super-Cache.
