ContentCaching

If true, the system purges content from the cache automatically when it needs disk space for other apps when free disk space runs low on the computer. Set to false to maximize effectiveness of Content Caching.

If true, the system caches the user’s iCloud data. Changes to this value don’t have an immediate effect. Clients may take some time to react to changes.

If true, the system caches non-iCloud content, such as apps and software updates. Changes to this value don’t have an immediate effect. Clients may take some time to react to changes.

If true, the system automatically activates the content cache when possible and prevents disabling it. If allowContentCaching is false, AutoActivation is also false.

Removing a profile that set AutoActivation to true doesn’t deactivate the Content Cache.

If true, the system automatically enables Internet connection sharing when possible and prevent disabling Internet connection sharing. DenyTetheredCaching overrides AutoEnableTetheredCaching. Tethered caching requires Content Caching.

The maximum number of bytes of disk space to use for the content cache. Set to 0 for unlimited disk space. Also serves as the upper bound to the PersonalCacheLimit.

The path to the directory used to store cached content. Changing this setting manually doesn’t automatically move cached content from the old location to the new one. To move content automatically, use the Sharing preference’s Content Caching pane. The value must be (or end with) /Library/Application Support/Apple/AssetCache/Data.

The system creates a directory and its intermediates for the given data path if it doesn’t already exist. The directory is owned by _assetcache:_assetcache and has mode 0750. Its immediate parent directory (.../Library/Application Support/Apple/AssetCache) is owned by _assetcache:_assetcache and has mode 0755.

The time interval in seconds the system uses to update the StatusContentCacheInfo declarative status item. The reporting interval can’t be less than 60 (1 per minute) or larger than 86400 (1 per day), defaults to 0 (off)

If true, the system disables Content Caching. This is the inverse of the allowContentCaching restriction in MDM. It overrides the AutoActivation key. Use this key to prevent launching the Content Caching service.

If true, the system disables tethered caching.

If true, Content Caching displays exceptional conditions (alerts) as system notifications in the upper corner of the screen.

If true, the system prevents the computer from sleeping as long as Content Caching is on (System Preferences > Sharing > Content Caching is on). Customers who want Content Caching to be as available as much as possible should turn this setting on.

An array of dictionaries that describe a range of client IP addresses to serve.

If true, the content cache provides content to the clients in the ListenRanges.

If true, the content cache provides content to the clients in the union of the ListenRanges, PeerListenRanges and Parents.

If true, the content cache offers content to clients only on the same immediate local network only. No content is offered to clients on other networks reachable by the content cache. If LocalSubnetsOnly is true, the system ignores ListenRanges.

If true, the Content Cache logs the IP address and port number of the clients that request content.

The reporting interval in seconds the system uses when ManagementStatusTarget is present. The reporting interval can’t be less than 60 (1 per minute) or larger than 86400 (1 per day), and defaults to 300 (1 per 5 min).

If the ManagementStatusTarget is an https URL, the system uses this field to determine how the connection is secured.

• no-cert: The system uses regular https processing using the built-in anchor certificates.

• signedByCACert: The system requires the https connection’s certificate to be signed by the certificate provided in the ManagementStatusCertificateReference field. If your organization has a CA infrastructure this is the best choice.

• specificServerCert: The system requires the https connection’s certificate to match the certificate provided in the ManagementStatusCertificateReference field.

The identifier of an asset declaration that contains the certificate the system uses to verify the security of the status reporting https connection. Required when ManagementSecurityConfig is set to signedByCACert or specificServerCert.

The target URL the system uses to send management statistics using an HTTP PUT request with a json dictionary as the payload. If the URL is an https URL (recommended) the ManagementSecurityConfig defines how the system secures the connection. The system sends the management statistics report to the target URL at an interval set by the ManagementReportingInterval value.

An array of the local IP addresses of other content caches that this cache should download from or upload to, instead of downloading from or uploading to Apple directly. The system ignores invalid addresses and addresses of computers that aren’t content caches. The system skips Parent caches that become unavailable. If all parent content caches become unavailable, the content cache downloads from or uploads to Apple directly, until a parent content cache becomes available again.

The policy to implement when choosing among more than one configured parent content cache. With every policy, the system skips parent caches that are temporarily unavailable. Allowed values:

• first-available: Always use the first available parent in the Parents list. Use this policy to designate permanent primary, secondary, and subsequent parents.

• url-path-hash: Hash the path part of the requested URL so that the same parent is always used for the same URL. This is useful for maximizing the size of the combined caches of the parents.

• random: Choose a parent at random. Use this policy for load balancing.

• round-robin: Rotate through the parents in order. Use this policy for load balancing.

• sticky-available: Use the first available parent in the Parents list until it becomes unavailable, then advance to the next one. Use this policy for designating floating primary, secondary, and subsequent parents.

An array of dictionaries describing a range of peer IP addresses that the content cache uses to filter its list of peers to query for content. The content cache only queries peers in PeerFilterRanges. When PeerFilterRanges is an empty array, the content cache doesn’t query any peers.

An array of dictionaries describing a range of peer IP addresses the content cache responds to. When PeerListenRanges is an empty array, the content cache responds with an error to all cache queries.

If true, the content cache only peers with other content caches on the same immediate local network, rather than with content caches that use the same public IP address as the device. When PeerLocalSubnetsOnly is true, it overrides the configuration of PeerFilterRanges and PeerListenRanges. If the network changes, the local network peering restrictions update appropriately. If false, the content cache defers to PeerFilterRanges and PeerListenRanges for configuring the peering restrictions.

The maximum number of bytes of disk space to use for the personal content cache. The content cache limits the maximum value to the CacheLimit value. Set to 0 to use the overall CacheLimit.

The TCP port number on which the content cache accepts requests for uploads or downloads. Set to 0 to pick a random, available port.

An array of dictionaries describing a range of public IP addresses that the cloud servers should use for matching clients to content caches.
