It take it you meant a -H, not -h...

Some time ago we switched over to use chunked transfer-encoding when you
upload from stdin, since the size cannot be known then. However, I just
recently was alerted that this (as you describe) particular use case is indeed
In this case, for you, curl will enable chunked transfer-encoding and upload
this accordingly. I have no idea why it "hangs". Possibly because the server
gets confused by both a chunked header (and chunked body) and a
Content-Length. I could not repeat a hang on my local test server, but I
haven't actually tried using the 7.11.0 release code.
I've adjusted the code in CVS to allow the chunked encoding to be possible to
switch off, which it couldn't in 7.11.0. If you get curl off CVS or a recent
daily snapshot, try this:
echo -en test |curl -T - -H "Transfer-Encoding:" -H "Content-Length: 4"
Seems to work for me.
