This is a PHP script to detect and embed small images inside CSS via the data: protocol and base64 encoding. The script also caches the image for further usage, avoding instances where the server recompiles the same image times and times again.

CSS Cacheer looks for image sources inside a CSS stylesheet and if the user's browser supports it, transforms that image into a data: image/png; based64 declaration. Applied on large stylesheets, it reduces the number of HTTP server requests, all image data residing inside the CSS stylesheet itself.

Other features, inherited from an order project called CSS-SSPP, include server-side imports, variables, constants, bases and nested-selectors.

Requirements:
- PHP
- Apche with mod_deflate and mod_rewrite enabled

Limitations:
- Application for small images only

What'New in this version CSS Cacheer v003:
- This update fixes a bug in the Nested Selectors plugin that prevented stylesheets containing quotes (eg. content:".";) from being successfully parsed.
