Windows DNS cache

But suit yourself. Personally I don't have any problems with my browsers. Actually, Firefox goes to the other extreme. If you don't set Network.dns.disablePrefetch and Network.dns.disablePrefetchFromHTTPS to false then FF will make DNS calls to links in the webpages you read, just in case you decide to visit them! And it gets worse. If you don't set Network.prefetch-next to false then FF will also load page content that you *might* decide to visit. It's sacrifing both efficiency and privacy so that it can look zippy on your next hop. |
