To add a little more information, I did some testing with older versions of
WordPress in combination with the http_api_transports to force a specific
transport ('streams', 'fsockopen', and 'curl'). I found the following
results:
3.6.1: cURL: Success fsockopen: Success streams: Success
3.7.1: cURL: Success fsockopen: Fail streams: Fail
3.8.1: cURL: Success fsockopen: Fail streams: Fail
Something clearly changed with the streams and fsockopen transports between
3.6.1 and 3.7.1. A diff of the class-http.php file shows the change was
substantial as the files are significantly different.
At this point I have concluded that my plugin will only work with sites
where cURL is available.
