If you have a collection of objects that you usually refresh at the same time, group them under a single cache tag. This way you can purge all content possessing this tag with a single request. You create your own cache tags using natural language, for example fall-sale. This may be more convenient than providing a technical identifier, such as URL or CP code.

Before you begin

• Make sure you properly assigned cache tags to the content you want to purge.

• Review Purge permissions.

• To optimize the use of cache tags for your organization, see Cache tag use cases.

🚧

Not for use with Cloud Wrapper

This purge method can cause unintended eviction of objects outside of the purge request, from all Akamai caching tiers, including Cloud Wrapper. This results in poor offload.

How to

1. Under Purge content by, select Cache Tags.

2. In the entry field, type at least one valid cache tag. All objects matching any of the tags you specify will be purged.

   Cache tag requirements

   • A single tag can't exceed 128 characters.

   • To insert multiple tags, press Enter, Tab, or , after each tag.

   • The maximum number of tags per cached object is 128. Any additional tags are ignored.

   • Cache tags are case-sensitive, for example, tag-abc and Tag-Abc are treated as distinct tag values.

   Allowed and disallowed cache tag characters.

   Allowed	Disallowed
   Alphanumeric	Angle brackets (< >)
   Ampersand (&)	Asterisk (*)
   Apostrophe (')	At sign (@)
   Circumflex (^)	Backslash (\)
