About
The ETag HTTP response header is an identifier for a specific version of a resource that is used for cache validation.
It enables browsers to verify whether a cached resource is still up to date by sending the ETag back to the server, which compares it with the current version and returns the resource only if it has changed.
Redirect is a web redirection technique that automatically sends visitors from one domain to another instead of displaying content on the original website.
It is typically implemented using 
HTTP 3xx status codes, 
HTML meta refresh tags, or 
JavaScript redirects.
