How to detect missing Content-Length response header?
Date: Thu, 19 Feb 2009 12:06:06 -0800
I'm using curl_easy_getinfo() with CURLINFO_CONTENT_LENGTH_DOWNLOAD in order to get the value of Content-Length. If the Content-Length header was not present in the response headers at all, curl still returns "0" with curl_easy_getinfo() returning CURLE_OK. That means there's no built-in way to detect Content-Length actually being 0, vs the Content-Length header not being sent.
Is there some other mechanism? If not, it looks like I'll have to check for the headers as they come in, using the HEADERFUNCTION callback.
