Suppose a very large website wants a mechanism by which clients access whichever of multiple HTTP servers is "closest" by some suitable measure. (a) Discuss developing a mechanism within HTTP for doing this. (b) Discuss developing a mechanism within DNS for doing this. Compare the two. Can either approach be made to work without upgrading the browser?

Show how to turn on native authentication and authorization services on the web server when a web client seeks access to restricted resources. Which of these two justifications for layered protocols do you find to be more convincing? Can you provide instances to support your claim?
A web client is required to first make use of the web server's native authentication and authorization services before they are allowed access to a web server's protected resources. Is there any additional benefit to using layered protocols except those listed here? It would be helpful if you could provide concrete examples to back up your claims.
