Ya, that's not a header as such... it's the chunked encoding length spec.
There's a better explanation available at [1] and [2] but basically for chunked
encode you specify the length of the chunk, in hex, on a line followed by \r\n.

The transmission is terminated by a 0 length chunk.  Form is: 0\r\n\r\n

I'm reasonably confident my implementation of it is is correct, wget, curl and
chrome all process it correctly, but if I've an error there I'm happy to
correct it and retest.
