What does the term "redirection" refer to in the context of proxies?

In the context of proxies, "redirection" specifically refers to the process of sending requests made to one server to another server. This is often done when a specific resource or service is more efficiently handled or available on a different server. By redirecting traffic, proxies can help manage load, enhance performance, or reroute users to new locations or servers without the end user needing to manually change their requests.

For instance, if a user attempts to access a website and that site has moved to a different server, the proxy can automatically redirect the user's request to the correct location. This function is crucial in network management, as it can facilitate seamless user experiences even in cases of server migration or maintenance.

The other options deal with different functionalities that proxies can perform but do not define "redirection" accurately. Blocking requests pertains to access control, duplicating requests relates to load balancing strategies, and logging requests is part of monitoring and analysis. However, none of these functionalities captures the essence of what redirection accomplishes in proxy operation.
