By setting an expiry time for the files on your Web site, you can go even farther than merely relying on the conditional GET and the 304 response that a server sends when a file has not changed; you can prevent the contact with the server from happening at all.

By setting an expiry time for the files on your Web site, you can go even farther than merely relying on the conditional GET and the 304 response that a server sends when a file has not changed; you can prevent the contact with the server from happening at all.

This is noticeably faster than even a conditional GET and a 304 response from the server since there is no round trip.
