Technically perhaps, but we have to implement this stuff in the time frame of yesterday.

Animated gifs are not always dynamic content, they are .gif files that don't change most of the time. Banner ads are fine to cache, due to the fact that when you aggregate a large user base who all hit the same area of the internet you quickly build up a good collection of the banner ads that area of the internet is sending out. We probably have a 60 to 70% hit rate on any banner adds on Yahoo and a few other major sites. Though the pointer in the referenceing page causes that page to be uncacheable, the pointed to (reference) is often quite cacheable and static, and often even an animated gif. -- Rod Grimes - KD7CAX - (RWG25) rgrimes@gndrsh.dnsmgr.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
