varnish

How R2G Tools, a dropped-domain search engine, was built with MongoDB, MySQL, CodeIgniter, Lighttpd, Varnish, and memcached running on three commodity servers.

Serve custom HTML error pages from Varnish using an inline C snippet to read files from disk, with fallback to default Varnish pages for non-5xx status codes.

A set of free, downloadable funny and slick HTTP 5xx error pages for Apache, Lighttpd, or Varnish — because server errors don't have to be boring.
