New Client Accelerator 600 Products Deliver Up to

Two Times the Performance Using 1/3 of the Rack Space

CacheFlow(R) Inc. (Nasdaq:CFLO), the leading provider of content intelligent networking solutions, today announced immediate availability of a new line of content acceleration appliances that provide the foundation for end-to-end, Enterprise Content Management. The new CacheFlow Client Accelerator 600 Series(TM) enables enterprises, government organizations and educational institutions to increase user productivity, reduce bandwidth costs, and scale existing network infrastructure to support increasing demands for streaming media and web content.

"CacheFlow is leading the way in providing a real-world content management solution for enterprise customers, " said Patrick Paczkowski, analyst at Current Analysis. "By storing both Internet and intranet content closer to end users at corporate and remote offices, enterprise organizations will be able to realize the benefits of emerging business applications and content to make their employees more productive."

CacheFlow's End-to-End Enterprise Solution

Setting the standard for content intelligent networks within the enterprise, CacheFlow's leading product portfolio allows an organization to evolve an existing intranet into a dedicated content distribution network -- securely connecting users at corporate headquarters, remote offices and business partners with the information and content they need. CacheFlow, in conjunction with leading Adaptive Content Exchange (ACE) partners, provides a comprehensive solution including content intelligent appliances, user based content filtering services, certified multimedia services, and management tools to enable enterprises to address their unique business requirements. CacheFlow's Enterprise Content Management solution includes:

-- Client Accelerator 600 Series -- Accelerate the delivery of intranet and
Internet content to end users by storing web and multimedia streaming content
at the edge of the network, closer to users. This reduces response times
associated with network latency and provides up to 60% reduction in WAN
bandwidth utilization.

-- Server Accelerator 700 Series -- Accelerate and scale intranet and extranet
web server farms by handling up to 95% of requests for HTTP and HTTPS content.
This dramatically reduces web server latency and improves user response times
by 50-80%.

-- Content Filtering Services -- Integrated content filtering services allow
administrators to easily implement corporate policies for managing and blocking
user access to inappropriate or unproductive web sites.

-- Multimedia Services -- Natively embedded support for the leading streaming
media formats optimizes live and on demand multimedia content, improves viewing
and listening quality, and reduces network infrastructure requirements.

-- CacheFlow Content Manager -- Allows organizations to intelligently
synchronize and manage content across a distributed network of content
accelerators, essential for enterprises that manage large volumes of
information.

-- Reporting -- CacheFlow accelerators support the popular log formats
including Squid, common log and W3C for exporting important log information
into a variety of third party utilities to facilitate management reporting and
decision making.

"Enterprise organizations are moving beyond just providing static web content to users," said Patrick Harr, vice president of Marketing at CacheFlow. "With the introduction of the Client Accelerator 600 products, customers can easily evolve their networks to dedicated content delivery networks capable of meeting the demands for both web content and streaming media services."
