etag

ETag (This is a community driven project)

ETag middleware for Hertz framework, inspired by fiber-etag.

The ETag (or entity tag) HTTP response header is an identifier for a specific version of a resource. It lets caches be more efficient and save bandwidth, as a web server does not need to resend a full response if the content was not changed. Additionally, etags help to prevent simultaneous updates of a resource from overwriting each other ("mid-air collisions").
