+ * Detect whether or not we have a SSL secured (HTTPS) connection
+ * connection to the browser
+ *
+ * It is thought to be so if you have 'SSLOptions +StdEnvVars'
+ * in your Apache configuration,
+ *     OR if you have HTTPS set to a non-empty value (except "off")
+ *        in your HTTP_SERVER_VARS,
+ *     OR if you have HTTP_X_FORWARDED_PROTO=https in your HTTP_SERVER_VARS,
+ *     OR if you are on port 443.
+ *
+ * Note: HTTP_X_FORWARDED_PROTO could be sent from the client and
+ *       therefore possibly spoofed/hackable.  Thus, SquirrelMail
+ *       ignores such headers by default.  The administrator
+ *       can tell SM to use such header values by setting
+ *       $sq_ignore_http_x_forwarded_headers to boolean FALSE
+ *       in config/config.php or by using config/conf.pl.
+ *
+ * Note: It is possible to run SSL on a port other than 443, and
+ *       if that is the case, the administrator should set
+ *       $sq_https_port in config/config.php or by using config/conf.pl.
+ *
+ * @return boolean TRUE if the current connection is SSL-encrypted;
+ *                 FALSE otherwise.
