+  module MongrelServer
+    # Implements a handler that can run Rails and serve files out of the
+    # Rails application's public directory.  This lets you run your Rails
+    # application with Mongrel during development and testing, then use it
+    # also in production behind a server that's better at serving the
+    # static files.
+    #
+    # The RailsHandler takes a mime_map parameter which is a simple suffix=mimetype
+    # mapping that it should add to the list of valid mime types.
+    #
+    # It also supports page caching directly and will try to resolve a request
+    # in the following order:
+    #
+    # * If the requested exact PATH_INFO exists as a file then serve it.
+    # * If it exists at PATH_INFO+".html" exists then serve that.
+    # * Finally, construct a Mongrel::CGIWrapper and run Dispatcher.dispatch to have Rails go.
+    #
+    # This means that if you are using page caching it will actually work with Mongrel
+    # and you should see a decent speed boost (but not as fast as if you use a static
+    # server like Apache or Litespeed).
+    class RailsHandler < Mongrel::HttpHandler
+      # Construct a Mongrel::CGIWrapper and dispatch.
