Hi Markus, sorry, but it doesn't work. :-( - Added this line in squid.conf - server squid3 reload - deleted IE cache restarted IE and open the website -> same error. Any other ideas? -- Marcel -----Ursprüngliche Nachricht----- Von: Markus Lauterbach [mailto:markus.lauterbach@xxxxxxxxxxxxx] Gesendet: Dienstag, 8.

I think, it should lool somehow like this: header_access Authorization allow all And restart your squid.
