When you're connecting through a proxy server you can't rely on fsockopen returning false
to indicate that the connection has failed. (This also applies to fgets and fwrite.)
To check whether the proxy succeeded in contacting the real target host, you need to look for the
http response code in the headers that get returned. Typically, if the proxy was unable to reach the
host, you'll find a line containing something like:
HTTP/1.0 503 Service Unavailable
