ssl is not detecting for cloudflare

[meshr]

My blog is behind cloudflare and if i use https to access it then it doesn't display properly because is_ssl() function doesn’t detect https. I added $_SERVER['HTTP_X_FORWARDED_PROTO'] variable check and it works now properly. Here is a fix for is_ssl() in my wp-includes/functions.php:

function is_ssl() {
	if ( isset($_SERVER['HTTPS']) ) {
		if ( 'off' !== strtolower($_SERVER['HTTPS']) )
			return true;
		if ( '1' == $_SERVER['HTTPS'] )
			return true;
	} elseif ( isset($_SERVER['SERVER_PORT']) && ( '443' == $_SERVER['SERVER_PORT'] ) ) {
		return true;
	}elseif ( isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && ( 'https' == $_SERVER['HTTP_X_FORWARDED_PROTO'] ) ) {
		return true;
	}
	return false;
}

You'll need to submit a .patch/.diff file for it to be considered for core. :)

Thanks for the report, meshr. This is something that comes up often, but is not something that will be fixed due to the nature of client-provided headers. See here for more info.
