Summary: HTTP POST from stdin does not work as expected

Initial Comment:
i'm trying to POST data from stdin via a pipe:
# some_command |curl --request POST --data - --url "http://server.example.com/post_handler"

the only thing that gets posed by this command is '-' instead of the whole stdin.
i know that a POST request requires to know and set the Content-Length in advance, so maybe there's a problem.
but even if i add the calculated length with --header "Content-Length: xxx" it sends nothing.

it would be ok, if curl buffers the whole stdin, calculates the conten-length and sends the request afterwards.

curl 7.19.6 (i686-pc-linux-gnu) libcurl/7.19.6 GnuTLS/2.8.5 zlib/1.2.3 libidn/1.15

Message:
doh - my fault.
sorry for bothering you.
i circumvented the problem by buffering the post, which was needed to
calculate the context length.

will stop reinventing the wheel now.

PS: thanks for --request parameter hint.

Message:
That's how --data works! If you want to send POST data to the peer that you
read from stdin, then you need --data @-!!

And note that --request POST is completely superfluous in that command
line. --data implies POST.
