Westborough, MA - January 31, 2000: Mangosoft, Inc. (NASDAQ BB:MGOF), developers of innovative software that leverages PC desktop systems to improve your Internet experience, today announced the release of CacheLink 2.0, the newest version of its software-based Web cache server. CacheLink stores frequently viewed Web pages for rapid retrieval by any computer connected to a company's local network, dramatically improving Internet and intranet performance. CacheLink 2.0 is explicitly designed for integration with shared Internet access devices, bringing the benefits of Web caching to small and medium sized businesses cost-effectively.

"Mango is committed to delivering software that leverages company equipment to significantly improve the efficiency and performance of an organization's Internet access," said Scott Davis, chief technology officer of Mango. "CacheLink 2.0 extends the capabilities of shared Internet access devices, enabling them to serve as LAN-based Web cache appliances in conjunction with PC desktops. The integration of CacheLink 2.0 with these shared devices, and other hardware products, offers a cost-effective solution for businesses that want high-speed Internet access, but also need to work within a budget."

Vendors can now easily add CacheLink's high-performance Internet access as a differentiating feature on hardware products, including shared Internet access devices, PCs and modems. Mango also today announced an agreement with Ramp Networks to bundle CacheLink on the award-winning WebRamp 350E shared Internet access devices as the preferred caching solution.

About Cachelink

CacheLink dramatically improves Internet and intranet performance by retrieving frequently viewed Web pages from other CacheLink users in a company's LAN instead of from the Internet. It complements the browser cache in each PC by efficiently linking them together into a single cache pool for all PCs. Performance measurements show CacheLink delivers Web cache hits, on average, 40 times faster than a non-cached 56K shared-modem. CacheLink users spend less time waiting for Web content and also free up Internet bandwidth, resulting in more available capacity.
