Can I stop you there already? If you intend to do "plain" HTTP, then you
really should not use curl_easy_send() as libcurl itself supports HTTP much
better using the proper curl_easy_perform() API and it will solve lots of
things you have to re-implement yourself otherwise.

That's not what 404 means. 404 means the request identified a resource that
doesn't exist. The request can still be perfectly understandable.

Since you didn't show the full code we can't tell. A quick guess would be that
they post to different URLs.
