Property Manager Name: Cache Tag
This adds a cache tag to the requested object. With cache tags, you can flexibly fast purge tagged segments of your cached content. You can either define these tags with an Edge-Cache-Tag header at the origin server level, or use this behavior to directly add a cache tag to the object as the edge server caches it. The cacheTag behavior can only take a single value, including a variable. If you want to specify more tags for an object, add a few instances of this behavior to your configuration.
Options
- tag (string; allows variables): Specifies the cache tag you want to add to your cached content. A cache tag is only added when the object is first added to cache. A single cache tag can’t exceed 128 characters and can only include alphanumeric characters, plus this class of characters:
[!#$%'+./^_`|~-]
