In my case I just save the remote address, but in your example below I suppose you redefined FRequest (and FResponse) to hide the private one in the ancestor, but what I don't understand is the C:=C+C and the need to set FRequest and FResponse to nil. You can remove the C variable stuff, it was for debugging purposes. I simply didn't remove it during the copy & paste. I set the variables to Nil after calling inherited (where the request is actualluy handled) so they are not inadvertently used in the OnDestroy of the datamodule.

I have code that needs to work with 3.2.2 and I do this: --- procedure TUserRPCModule.HandleRequest(ARequest: TRequest; AResponse: TResponse); Var C : String; begin FRequest:=aRequest; FResponse:=aResponse; try C:=FRequest.Content; C:=C+C; inherited HandleRequest(ARequest, AResponse); finally FRequest:=Nil; FResponse:=Nil; end; end; Bye -- Luca ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
