Apache Reference: mod_proxy, NoCache

NoCache

Targets for Which the Proxy Will Not Perform Caching
Syntax: NoCache target [target ...]
Example: NoCache .foo.dom 192.168.1.0/21
Since: Apache 1.1

This directive specifies a space-seperated list of targets - that is, subnets (``192.168.1.0/21''), IP addresses (``192.168.1.1''), hosts (``www.==foo.dom''), and domains (``.foo.dom'') - for which the proxy will not cache documents. This directive is mainly useful for Apache proxy servers that reside within intranets.
