+    # ERBHandler evaluates an ERB file and returns the result.  This handler

+    # ERBHandler supports GET and POST methods.
+    #
+    # The ERB file is evaluated with the local variables +servlet_request+ and

+    # WEBrick::HTTPResponse respectively.
+    #
+    # Example .rhtml file:

+    #   Request to <%= servlet_request.request_uri %>

+    #   Query params <%= servlet_request.query.inspect %>
