That's fine, just don't reply to an existing message when you start a new

libcurl can handle automatic decompressing on downloads but not the reverse,
namely what you want. You might be able to do what you want by setting a
Content-Encoding: gzip in the request along with a 100-continue header.
The server then has a chance to abort the transfer if it doesn't support
gzip, but I suspect some servers won't support this. I'm not sure what
other way you can tell if the server supports gzip or not.
