Proxy servers operate at the Application Layer, which is the seventh and highest layer of the OSI model. This layer deals with the interface between the network and the user's applications, and it includes protocols such as HTTP, FTP, SMTP, and Telnet. Proxy servers work by intercepting and forwarding application-layer messages between clients and servers, allowing them to filter and modify the requests and responses as needed. By operating at this layer, proxy servers can provide various benefits, such as caching, filtering, load balancing, and anonymity.
