Hello friends

Can any one let me know what is an ETag and how does it work?

Well, it’s a mechanism that HTTP provides for web cache validation – specifically it allows for a client to make a request that is conditional on whether the content it’s requesting from the server has changed or not. If it hasn’t changed, then this allows the resource to be fetched from cache more efficiently, saving bandwidth.
