WP CSS-Streamliner: Streamline and optimize and compress your CSS file with this Wordpress plugin to improve your blog’s performance.

WP-CSS-Streamliner has the following features:

• Grabs all <link> tags from your pages in real-time and transforms them into one new one pointing to a highly optimized combined CSS file
• Performs gzip compression on the optimized CSS file
• Exclude mechanism to keep certain CSS out of the optimization process, for example print CSS files, alternate stylesheets or IE specific CSS within conditional comments
• Caches different combinations of CSS on a per-page basis. Every combination will be cached and served once
• Rewrites image URL's in CSS to absolute ones in order to make CSS coming from different directories still work properly when served from one location
• Automatically excludes CSS served from other hosts (no need to use the exclude mechanism for this)
• Force-refresh option to refresh the cache in case of trouble
