Origin
From Middle English procuracie via Anglo-French, from Latin procuratio (management for another); shortened in English to proxy.
History
Shareholders vote by proxy; networks route through proxy servers; scientists use proxy data such as tree rings for past climates. The shared idea is representation at a distance. Tech and civics both keep the word busy, which feeds search traffic.
