In an HTTP request, the headers are separated from the body by an 
empty line. Headers use CR/LF line endings, so the body is always 
preceded by a 0D 0A 0D 0A sequence. It looks like your code is 
not snipping the last 0A.

Where did the getchar method come from? There is no mention of it 
in Phobos. Perhaps you could try the read(out ubyte) method?
