Scheduling updates to local cache content

Help | Content Gateway | Version 7.7.3

To further increase performance and to ensure that HTTP and FTP objects (requested from HTTP clients) are fresh in the cache, you can use the Scheduled Update option to configure the proxy to load specific objects into the cache at scheduled times.

To use the Scheduled Update option:

Specify the list of URLs that contain the objects you want to schedule for update, the time the update should take place, and the recursion depth for the URL.

Enable the Scheduled Update option and configure optional retry settings.

See Configuring the Scheduled Update option for more information.

Content Gateway uses the information you specify to determine the URLs for which it is responsible and, for each URL, derives all recursive URLs if applicable. It then generates a unique URL list. Using this list, the proxy initiates an HTTP GET for each unaccessed URL, ensuring that it remains within the user-defined limits for HTTP concurrency at any given time.


	Note The system logs the completion of all HTTP GET operations, enabling you to monitor the performance of this feature.

The Force Immediate Update option that enables you to update URLs without waiting for the specified update time to occur. You can use this option to test your scheduled update configuration. See Forcing an immediate update.
