When typing cnn.com in the address bar, it takes seven seconds until browser responds at all. It hangs a couple of times more as well during the load process, before showing the page without any specific problems in rendering. Browser is unresponsive during hang. Even "pizza whirl" loading icon stops - menus impossible to click on. Tested on both FreeBSD and Windows XP with clean profiles - same problem occurs. Using WPAD like this: From dhcpd.conf: option wpad code 252 = text; option wpad "http://wpad.hostname.com/wpad.dat\n"; (Had to include the \n at the end of the string to circumvent a bug in IE6+, documented here: http://www.squid-cache.org/Doc/FAQ/FAQ-5.html#ss5.11 $ curl wpad.hostname.com/wpad.dat function FindProxyForURL(url,host) { if( isPlainHostName(host) || url.substring(0, 7) != "http://" || isInNet(host,"188.190.195.0","255.255.255.0") || isInNet(host,"10.0.0.0","255.255.255.0") ) { return "DIRECT"; } else { return "PROXY 188.190.195.17:8118; DIRECT"; } } Note: Ip's and hostnames obfuscated. Reproducible: Always Steps to Reproduce: 1. Set up WPAD as described 2. Visit website with uncached hostname 3. Observe hangs Actual Results: Browser hangs several times for 5-8 seconds before displaying website as normal Expected Results: Quick browser display. My proxy is a Privoxy more or less default config based on Suse 9.2 Professional

I found out why the browser hanged: It's related to the time for the browser to get a lookup of the specific hostname to be browsed. Our setup at work was b0rked, which made it ask directly to the root dns servers, which in effect would make a lookup take a long time. I realized this, fixed our internal dns config to ask upstream isp's dns servers, and then the resolving was much faster. Now the long hang is gone in Firefox when typing in addresses. So suggest you look into it there. Dig used before change in internal DNS: $ dig @192.190.193.11 www.ikke.no ; <<>> DiG 9.3.1 <<>> @192.190.193.11 www.ikke.no ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 22346 ;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 4, ADDITIONAL: 1 ;; QUESTION SECTION: ;www.ikke.no.
