What exactly does FORBID_REUSE do in libcurl, specifically in the PHP implementation of CURL if there is any difference. I found documentation for it here: http://scriptbasic.com/html/texi/mod_curl/mod_curl_3.46.html, but that really doesn't help too much. It just says "if you don't know what you're doing, don't use it."
Well, I'd like to know what I'm doing.
