ISP-CACHING Digest for Friday, August 04, 2000. 1. Re: Caching Products and Skycaching 2. Re: Caching Products and Skycaching 3. Re: Caching Products and Skycaching 4. Re: Caching Products and Skycaching ---------------------------------------------------------------------- Subject: Re: Caching Products and Skycaching From: "Tim Jung" <[EMAIL PROTECTED]> Date: Fri, 4 Aug 2000 20:22:40 -0500 X-Message-Number: 1 I don't think currently many of the caching products can cache streaming media formats. Squid does not currently offer this that I have heard about. I am not aware of any other than what Inktomi's box in partnership with Real Networks that can do it. Real Networks has a caching proxy software package out in beta but nothing firm yet. These are the only 2 that I am aware of currently. If there are others let me know.

If you go to StreamingMedia.com (the guys who sponsor the Streaming Media = Shows) you can see several startup/alternate model streaming companies who = were at the Streaming Media Show in NYC about 6 months ago....I spent 3 = days there and saw several new ideas for streaming technologies... I also know that there are several new products coming for streaming of MS = Media, so when searching for streaming, keep in mind that there are some = products that do Real exclusively and some that only do MS.
