caches generated content on disk if an etag response header is set; if the backend sends an already cached etag, the backend is closed and the file is sent directly. Please note: This will not skip the backend, as it will need at least the reponse headers. *Hint:* Use a cron-job like the following to remove old cached data, e.g. in crontab daily:

			 find /var/cache/lighttpd/cache_etag/ -type f -mtime +2 -exec rm -r {} \;

*Hint:* Have a look at mod_deflate to see this module in action. cache responses based on the ETag response header directory to store the cached results in This blocks action progress until the response headers are done (i.e. there has to be a content generator before it (like fastcgi/dirlist/static file). You could insert it multiple times of course (e.g. before and after deflate). setup { module_load "mod_cache_disk_etag"; } cache.disk.etag "/var/lib/lighttpd/cache_etag"
