Configuration options on a mobile device running the Android operating system allow specification of an intermediary server for network traffic when connected to a wireless network. This server, acting as a gateway between the device and the internet, intercepts requests and responses. For example, a user might enter a specific IP address and port number within the Wi-Fi settings to route all web browsing activity through a designated machine.
Implementing this functionality provides several advantages, including enhanced security through traffic filtering and potential access to region-restricted content. Organizations utilize this for content control and monitoring employee internet usage on company networks. Its historical context involves the broader evolution of network security and access management practices.
