cache-enable

Tells the proxy that an object is cacheable. As an example, if it appears in the object <Object ppath="http://.*">, then all HTTP documents are considered cacheable as long as other conditions for an object to be cacheable are met. 

cache-auth

Specifies whether to cache items that require authentication. If set to 1, pages that require authentication can be cached also. If not specified, defaults to 0. 

query-maxlen

Specifies the number of characters in the query string the “?string” part at the end of the URL that are still cacheable. The same queries are rarely repeated exactly in the same form by more than one user, and so caching them is often not desirable. That’s why the default is 0. 

The maximum possible value of query-maxlen is limited by the fact that the total length of the request URI, including the query string as well as the encoding extensions ("[gz]" or "[cmp]") used internally by the Proxy server, cannot exceed 128 bytes.

min-size

The minimum size, in kilobytes, of any document to be cached. The benefits of caching are greatest with the largest documents. For this reason, some people prefer to cache only larger documents. 

max-size

The maximum size in kilobytes of any document to be cached. This setting allows users to limit the maximum size of cached documents, so no single document can take up too much space. 

log-report

Used to control the feature that reports local cache accesses back to the origin server so that content providers get their true access logs. 

cache-local

Used to enable local host caching, that is, URLs without fully qualified domain names, in the proxy. If set to 1, local hosts are cached. If not specified, it defaults to 0, and local hosts are not cached.
