I was able to come up with an 'ugly' workaround for now. I can ignore the
below raised error, reset the content length to the compressed length, and
continue processing. Doing this will send the content-length of the
uncompressed message, but still allow me to write to the stream, send the
request, and receive the response. If anyone has a better suggestion I'd
still love to hear it.
Thanks
