Yes, that works:
wget -O /dev/null
http://server.domain:8080/Home.html
--2008-08-28 09:23:01--
http://server.domain:8080/Home.html
Auflösen des Hostnamen »server.domain«.... 127.0.0.1
Verbindungsaufbau zu server.domain|127.0.0.1|:8080... verbunden.
HTTP Anforderung gesendet, warte auf Antwort... 200 OK
Länge: nicht spezifiziert [text/html]
In »/dev/null« speichern.
Of course we can send you the complete stacktrace and netstat-output via email.
Thank you and with best regards
