Mark, I know it refreshes when you change it if you have a page open and also when you open the browser it downloads the autoconfig file. I tested this by using Webanalyzer and watched the hits to my config.proxy from our webserver. 1/2 a million hits in around 10 minutes. About 600 user online at any one time where we use it.

Does anyone know how often IE refreshes the autoconfig info? Is it with each link or browser session? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Mike Coles Sent: Sunday, November 24, 2002 9:40 AM To: [EMAIL PROTECTED] Subject: RE: Load Balancing SquidGurad Servers > Chris, > Yes we have been doing it for some time now to my understanding but we get > weird problems.

Not proficient in javascript so here's some pseudo-code. If even(time.second) { proxy 1.2.3.4:3128; proxy 1.2.3.5:3128} else { proxy 1.2.3.5; proxy 1.2.3.4:3128} Or based on a random number if even(random()) ...... You could divide the random numbers up into different groups if your had more than 2 servers Mike coles 'bluelip' ********************************************************** This message was virus scanned at siliconjunkie.net and any known viruses were removed.
