That would be a generally good approach to work with HTTP 1.1-compliant
posts, AFAIK.

(We'll work on getting the next release of libcurl use as few write()s as
possible so it might go back to the previous behavior for you then...)

I find that very odd. In curl's test suite, we have our own HTTP server code
as well, and that works fine with all curl versions 7.10.2, 7.10.3 and
7.10.4.

It sounds as if you've made a mistake somewhere.

No. There is an "acknowledge" system in HTTP 1.1 called the Expect:
100-continue, but 1) libcurl only uses it by default for formposts and 2) it
times out if no 100 continue (or a failure code) is returned rather soon.

I don't know either.

I think it is hard to say if you've done an OpenSSL error or some other plain
data/socket related error. I do however believe that libcurl does it right,
since posting (using SSL or not) works fine on a large amount of servers all
over.
