HttpWorkerRequest.GetBytesRead() always returns 0

Question

Anyone know why HttpWorkerRequest.GetBytesRead() always returns 0, even during and after a file upload? Would like to use this method to build a progress bar.

"This API supports the .NET Framework infrastructure and is not intended to be used directly from your code."

so probably this only returns this on a certain moment in the pipeline, but as stated by MS I would not try to use it since it's not supported ...
