Now you can use wallabag behind reverse proxy (i.e Squid or Varnish)
without problem with urls like wallabag.example.com:8080.
$serverport = (!isset($_SERVER["SERVER_PORT"])
|| $_SERVER["SERVER_PORT"] == '80'
+ || $_SERVER["SERVER_PORT"] == HTTP_PORT
|| ($https && $_SERVER["SERVER_PORT"] == '443')
|| ($https && $_SERVER["SERVER_PORT"]==SSL_PORT) //Custom HTTPS port detection
? '' : ':' . $_SERVER["SERVER_PORT"]);

+// Change this if http is running on nonstandard port - i.e is behind cache proxy
+@define ('HTTP_PORT', 80);
// Change this if not using the standart port for SSL - i.e you server is behind sslh
@define ('SSL_PORT', 443);
