Asyn function not working with HTTPS

Line 123 in 21643a1

$fp = fsockopen($parts['host'], isset($parts['port']) ? $parts['port']:80, $errno, $errstr, 30);

If my website is forced to HTTP though server, then fsocket is not working.. And errors not logged..

Did you check your php error log file?

There are no errors at all.
However, after digging deeper and changing the code, i understood that server responds with a 302 HTTP status (to the HTTPS url).
fsockopen can't properly work with redirections.
When i change fsockopen to use SSL, then server return 400 HTTP status.
