    # ERBHandler evaluates an ERB file and returns the result.  This handler
    # is automatically used if there are .rhtml files in a directory served by
    # the FileHandler.
    #
    # 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 %>
