CSS-JS-Booster
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
