HTTP_StaticMerger - automatic gluing of CSS and JS files for quick loading
The HTTP_StaticMerger library allows you to automatically “merge” a set of static files (CSS and JS) and, thus, speed up page loading, saving HTTP requests. The library is recommended to be used in conjunction with a reverse proxy cache to minimize response time. Opportunities:
Processing import directives and removing comments from code, which saves traffic.
"Merged" URL depends on the modification time of its files.
Support for HTTP headers If-Modified-Since, If-None-Match, Etag.
Work under very high load (when using a reverse-proxy server with a caching module, for example, nginx)
