Hi, 2 of my users access my server through the same ISP who (I presume) uses Squid. Sometimes the browser connects with no problem, but both of these users have sporadic occurrences of the browser stalling. (It just says 'Loading' but never loads) My Server runs from our office but the National Telcoms Provider does not believe in static IPs, (we are in South Africa) therefore we have to run a Dyndns account to keep track of our IP. My theory is that the Clients' ISP is caching our content and causing the stall. Rebooting the Server's ADSL modem/router allows both of these users to re-access the server and my theory is that the change of IP address after the reboot bypasses the clients' ISP's cache. What I would like to know is if there is any way for the clients to clear the cache? Not the browser cache, but the squid cache on the ISP's machine. Alternatively, if you feel that my theory is a pile of horse, could you suggest what else might be happening? Thank you, Dave Coventry
