SKYCACHE ANNOUNCES COMAPTIBILITY WITH CACHEFLOW PRODUCT FAMILY
New Level of Efficiency For ISPs and Backbone Providers

Laurel, MD (November 9, 1998) - SkyCache Inc., the world's premier high-speed datacasting company, today announced that CacheFlow Inc.'s family of industry-leading network caching appliances is certified SkyCache Compatible. Customers will now be able to deploy the industry's highest performing cache appliances in conjunction with the SkyCache service to improve the speed, reliability, scalability, and the bandwidth usage of their networks.

CacheFlow eliminates the extreme delay associated with Web page downloads. The company's network caching appliances, deployed at the edges of the network, speed information to users while reducing unnecessary network traffic. SkyCache provides an innovative satellite-based service for delivering updated Web content to CacheFlow appliances.

"A New Level Of Efficiency"
"CacheFlow's unique focus on eliminating the World Wide Wait delivers tremendous value for ISPs, backbone providers and enterprises," says Doug Humphrey, president and CEO of SkyCache. "The combination of CacheFlow's appliances and SkyCache's cost-effective broadcast service will bring a new level of efficiency for ISP networks."

"SkyCache is delivering an innovative service at a time of great industry change," said Kelly Herrell, vice president of Marketing for CacheFlow. "As the market continues its rapid adoption of caching appliances, we look forward to working with SkyCache to deliver cost-effective solutions to our shared customers."

How the Solution Works
Internet access providers will continue to deploy CacheFlow appliances at Points-Of-Presence (POPs). Web data is delivered via SkyCaches's satellite broadcast service to the CacheFlow appliances. As a result, end users will experience swift delivery of Web pages since they are cached close to users at the edges of the network, and access providers will leverage the cost-effective SkyCache service to populate the cache.

SkyCache, through a combination of its patent-pending Reactive Caching system and cache pre-population, provides superior performance by supplementing a stand-alone cache with high-quality data delivered by satellite broadcast technology. The SkyCache Release 1.0 cache turbo-charging service enables ISPs to add more customers to existing leased line capacity and deliver substantially faster web page response times in many cases

Powered by the patent pending CacheOS, CacheFlow products are appliances specifically architected for network caching. As dedicated devices, they provide the industry's leading cache performance in highly reliable rack-mounted hardware configurations. Each product in the CacheFlow line is designed to satisfy different network needs, such as differences in workload, scalability and high-availability requirements. CacheFlow products install in minutes, are self-tuning, and require zero administration.
