CacheNegotiatedDocs

Allow Caching of Content-Negotiated Documents
Syntax: CacheNegotiatedDocs
Example: CacheNegotiatedDocs
Since: Apache 1.0

This directive allows proxy servers to cache content-negotiated documents. As a result, clients behind those proxies may be able to retrieve versions of the documents that are not the best match for their abilities. This directive applies only to requests that come from HTTP/1.0 browsers. HTTP/1.1 provides much better control over the caching of negotiated documents, and this directive has no effect in responses to HTTP/1.1 requests.
