Hello, Have a look at the different "ad.doubleclick.net" addresses included in the web site. Find out the ip address and put them in your /etc/hosts file like this: 206.65.183.95 ad.doubleclick.net 206.65.183.95 uk.doubleclick.net 206.65.183.95 ad.uk.doubleclick.net 195.154.195.154 ad.fr.doubleclick.net This will solve the loading time of the different websites with konqueror, firefox etc( sticking to load 90% of the images of the web site). This issue doesn't seem to exist when you use Opera. Kind regards Jens On Thu, 15 Apr 2004 08:36:17 +0100 Matthew Seaman <m.seaman@infracaninophile.co.uk> wrote: > On Wed, Apr 14, 2004 at 08:43:53PM +0000, Travis Troyer wrote: > > I am running FreeBSD 5.2.1-Release on two systems, a server that acts as a NAT > > Gateway for my cable service, and a client.
