 Replying to [comment:3 twim]:

 like something that should not happen. Maybe it's even a bug.

 Do you mean a bug in the fronting service, or a bug somewhere else in
 meek-client?

 I would guess, that with a POST, the http client would omit `Content-
 Length`, and send `Transfer-Encoding: chunked`, then send a zero-length
 chunk if there were nothing to send. But I haven't checked.

 I'm still planning to merge your patch, because it looks like the right
 thing to do.
