The Harvest Cache and Httpd-Accelerator

Complements of the University of Southern California

The Harvest hierarchical object cache, an element of the Harvest Harvest Information Discovery and Access System, offers high performance proxy-http caching for Mosaic, Netscape, Lynx, and other Web clients. The Harvest httpd-accelerator improves performance of your NCSA 1.4 or Netscape Netsite Web servers by a factor TEN. That's right, if your httpd is swamped, try ours.

Both the cache and httpd-accelerator install easily, as described below. The current version is cached-2.1pl0

Cached-2.1 AVAILABLE

The Harvest cache developers now offer cached-2.0
