#
#        CacheRoot directive:
#
#        Specify the directory that the server will use for caching files.
#        If this directory is not specified, the proxy server will not attempt
#        to cache documents.
#
#        NOTE: If this directive is specified using the Configuration and
#              Administration forms, the directory will be created automatically.
#              If you define the directory by manually editing the configuration
#              file, you need to create the directory with the appropriate
#              permissions to enable the server to cache documents in it.
#
#        NOTE: You MUST also turn "on" the Caching directive.
#
#        Default:  .none.

# Example:
CacheRoot       c:\www\cache

#
#        CacheDefaultExpiry directive:
#
#        Specify the expiry date for files which do not include an explicit
#        expiry date and do not have a last-modified date that would allow us
#        to compute an expiry based on the CacheLastModifiedFactor. This is
#        most useful for protocols that do not have any way to transmit this
#        information, such as FTP or Gopher.
#
#        NOTE: The default expiration for HTTP is 0. HTTP should be kept at 0
#              because many script programs don't give an expiration date, yet
#              their output expires immediately. A value other than zero may
#              cause problems.
#
#        Defaults:  http:*    0 days

#        Specify how long the proxy cache should keep files which have not

#        the cache longer than this will be removed during garbage collection.
#
#        Default:  .none.

......... .... .......... ........ .. ......... ........ . ....... ....... .. ...... .......... ......:

#
#        CacheLimit_1 and CacheLimit_2 directives:
#
#        The caching system has two limits for filesizes. The upper limit
#        (CacheLimit_2) specifies the maximum size for any file that will be
#        cached. The lower limit (CacheLimit_1) is used by the garbage-collection
#        algorithm to decide what pages to remove from the cache. Any files smaller
#        than the lower limit will not have their size considered when the server
#        decides what files to remove from the cache; files larger than the
#        lower limit are progressively more likely to be removed from the cache.
#        The value for CacheLimit_1 and CacheLimit_2 can be specified in
#        bytes (B), kilobytes (K), megabytes (M), or gigabytes (G).
#
#        Default:  CacheLimit_1  20 K
#                  CacheLimit_2  400 K
#        Syntax:   CacheLimit_1  .bytes. .B|K|M|G.

# Example:

#        CacheOnly and NoCaching directives:
#
#        The server allows control over the files to be cached in two ways.
#
#        CacheOnly - specifies a set of URLs which will be considered for
#                    caching (URLs not in that list will never be cached)
#        NoCaching - specifies a set of URLs which must never be cached,

#
#        Default:  .none. (for both CacheOnly and NoCaching)

#
#        Gc (Garbage Collection) directive:
#
#        In order for a caching proxy server to function efficiently, it needs to
#        sweep through the cache and remove out-of-date files on a regular basis.
#        This is called 'garbage collection'. It should only be turned "off" in
#        special circumstances, such as during an extended network outage.
#
#        Default:  on
#        Syntax:   Gc .on | off.
Gc on

#
#        GcDailyGc directive:
#
#        Because garbage collection can take a significant amount of CPU resources,
#        it should be scheduled to take place when the load on the proxy server is
#        low. Use this directive to specify the time for garbage collection, using
#        a 24-hour clock; this will be assumed to be local time (not GMT).
#
#        Default:  03:00
#        Syntax:   GcDailyGc .hh:mm.
#
# Example:

GcDailyGc 03:00

#
#        GcMemUsage directive:
#
#        Used to restrict the amount of memory used by the garbage collection
#        process. Memory usage is specified in Kbytes (only). Setting this to
#        a small value will cause garbage collection to be extremely inefficient.
#        The minimum value is 20.
#
#        Default:  1000
#        Syntax:   GcMemUsage .Kbytes.
