If you get data together with the redirection, mabe it is not a bug that you get requestdone twice? > I've discovered another issue in that it doesn't seem that > the RcvdStream is being cleared.

Then when you receive data, the data is written from the start of the stream, overwriting previous data if there are any. If you use a TMemoryStream, you can use Clear or SetSize, this will also delete old data. You can also delete the stream and make a new stream.
