Try this:

Curl normally sends its entire request in two write()s. The first write() is
everything except the last CR-LF. Then it sends the final CR-LF separately.
The reason for this, is that this way enables curl to fill in custom headers,
cookies and whatever in between the write()s.

So what you see is the first package. The second package should come later.
However, if there's a TCP problem somewhere along the "road", it wouldn't
surprise me if you can get this to work by sending everything in one single
shot. (You only need to modify the curl source code slightly to test this
theory -- of course you'll disable a few features but this is for testing.)
