6.4 Using the Cache as an httpd accelerator

 

The httpd-accelerator is a specially configured Harvest cache that intercepts incoming HTTP requests, on average doubling your performance. Requests that miss and dynamically evaluated queries are forwarded to your httpd for evaluation. Requests that hit the accelerator are serviced blazingly quickly because the Harvest cache is implemented much more efficiently than existing HTTP implementations.

The httpd-accelerator is compatible with both the CERN and the NCSA implementations of httpd. For more information, see the distribution package.

Note that the Cache can function either as an httpd-accelerator or as a proxy cache, but not both at the same time. We disallow a cache from being used in both modes simultaneously because the Cache performs best when dedicated to a single use. If you want to have both functions, you need to two cached processes.
