IMPORTANT: The Content Pin settings page is applicable only for cache devices and appears in the Device Configuration Manager page. Pinning does not appear in the Group Configuration Manager.
Pin Options:
Enable Pin List: Check this box to activate pinning on the device. For more information regarding what pin lists are and how they function, see the main Velocity CDN Documentation.
NOTE: This option affects only the pinning of objects on the device. It has no effect on whether objects are cached unless the pin type is set to Bypass.
Prevent Purging of Pinned Objects: You can start the purge with this option selected to purge everything from the device's cache except for the content which you have pinned.
Pin List Insert:
URL Mask: Type a complete or partial URL pattern. A single URL mask might apply to a large set of URLs, or it might be so specific that only a single file on the Web matches it. For more details, see the Excelerator 2.1 Administration Guide.
Pin Type: Specify whether and how the device will cache objects that match the URL mask:
Normal: The device handles objects matching the mask in the same way it handles any other requested objects. In other words, objects are cached but not pinned.
Cache: The device keeps the pinned objects in cache as long as possible, although they might be written to the device's hard disk.
Memory: The device keeps the pinned objects in memory as long as possible, writes them to disk when memory gets too full, and places them back in memory as soon as they are requested by a user of the cache.
Bypass: The device does not cache the objects. In other words, you can use this option to prevent objects from being cached.
Pin Links: Specify how many link levels the device will follow the pin type rule you've established.
Pin Images: Pin image files that reside on a different host than the page requested.
Refresh Frequency/Time: This setting determines the start time for a pre-population job that fetches the specified URL.
Insert: After you have defined all of the pin settings, click the Insert button to add the specified URL Mask to the Pin List below.
Pin List: Shows all of the URL Masks and associated pin settings that you have created for the device.
