There seem to be three solutions for transparent web-caching: 1 a web-cache between two routers, all traffic is routed through it. 2 a l4 switch between two routers, all traffic is routed through it. The l4 switch redirects web-requests to a www-cache. 3 a web-cache connected to a router which uses policy routing to direct web-requests to it. 1 is extremely ugly and impossible at high traffic levels 2 is an extra device in your network which needs to be managed and is often difficult to implement in a WAN environment (our core routers don't have (fast-)ethernet interfaces.) 3 is the preferred solution but you need to run 11.3 or 12.0 for it. These software versions support fast-switched policy routing. Most ISPs currently rely on 11.1CC features and thus can not upgrade to 11.3. The wait is thus for a stable release of 12.0. -- Steven In your mail from 17-11-1998 you write:In article <19981117091400.D9778 () skriver dk>, Jesper Skriver <jesper () skriver dk> wrote; } Why use things like this, use a default route to a HSRP address ... That could be. But they (appliance venders) haven't shown it at this point, afaik. They simply shows a veiw of cache appliance and l4 switch sitting between 2 routers. Why? -- Katsuhiro Kondou
