Create and Manage Caching Rules in Rackspace CDN

Suggest Edits

Caching rules are designed to determine how long your content should
live on the edge nodes before the origin is checked for an update. If
your content changes frequently, you might want to set up a time to live
(TTL) rule that pulls content from the origin every few minutes. If your
content does not change frequently, we suggest you set a longer TTL of
12-24 hours.

When you create multiple rules, you must order rules from least specific
to most specific.

For more information about rules, see the following sections and
Rackspace CDN edge
rules.

After you create your service, you enter caching rules in the Caching
Rules section of the CDN service page.

      the unit for the TTL.
