+ # is automatically used if there are .rhtml files in a directory served by

+ # ERBHandler supports GET and POST methods.
+ #
+ # The ERB file is evaluated with the local variables +servlet_request+ and
+ # +servlet_response+ which are a WEBrick::HTTPRequest and
+ # WEBrick::HTTPResponse respectively.
+ #
+ # Example .rhtml file:
+ #
+ # Request to <%= servlet_request.request_uri %>
+ #
+ # Query params <%= servlet_request.query.inspect %>
+
+ class ERBHandler < AbstractServlet
