Hi list, is there any special config I need to allow java content? CentOS 6.3 x64 Squid 3.1.10 I can't get this Java applet: (Software-Zertifikat - Login) https://www.elsteronline.de/eportal/Oeffentlich.tax But only with Windows 2003 and IE8! Win7/Win2008 with IE9 works fine. With Win2003 IE tells me, that no Java was found on this machine. When I use a direct connection via firewall instead of squid proxy, it works fine. I found some "allow java" configs, but they don't work in this case. acl Java browser Java/1.1 Java/1.2 Java/1.3 Java/1.4 Java/1.5 Java/1.6 Java/1.7 acl default_allowed_useragents browser (Java) acl Durchgang url_regex .i \.jar$ http_access allow Java http_access allow all default_allowed_useragents http_access allow Durchgang all Thanks for help -- Marcel
