What is proxy in the sense of mobile network?

In the context of mobile networks, a proxy is an intermediary server that acts as a gateway between a user's device and the internet. It processes requests from the device, forwarding them to the appropriate web servers, and then relays the responses back to the device. Proxies can enhance performance through caching, improve security by hiding the user's IP address, and enable content filtering or access control. They are commonly used in mobile networks to optimize data usage and manage bandwidth.
