validate_​entity_​tag

Behavior name: Validate Entity Tag (ETag)

Instructs edge servers to compare the request's ETag header with that of the cached object. If they differ, the edge server sends a new copy of the object. This validation occurs in addition to the default validation of Last-Modified and If-Modified-Since headers.

You can specify whether this behavior should support only strong ETag values, ignoring weak ETag and always returning a full response, or weak values should also be accepted. For more details, see the RFC Standard.
