WEBrick is an HTTP server written in Ruby that uses servlets to extend its capabilities. Built into WEBrick are four servlets, handling CGI, ERb, file directories, and a generic Proc servlet. These are built on an abstract servlet class that makes it easy to build your own WEBrick servlets. You will need either Ruby 1.8 or an older version of Ruby with WEBrick installed.
