Homonym: Proxy (Substitute)
A "Proxy" is an intermediary that acts on behalf of another person or entity. In computing, a proxy server forwards requests from clients to other servers, allowing users to access resources while hiding their IP addresses. This can enhance privacy and security, as well as improve performance by caching data.
In legal terms, a proxy allows one person to authorize another to act on their behalf, often in voting situations. For example, in corporate settings, shareholders may use a proxy to vote on company matters without attending the meeting in person, ensuring their opinions are represented.
