Method and apparatus for emulating web browser proxies

摘要

A user device disposed on a local area network (LAN) requests a proxy auto-configuration file from a first proxy server. Where the first proxy server is not present on the LAN, a second proxy server on the LAN intercepts the request and responds to it by causing a replacement proxy auto-configuration file to be sent to the user device. The user device utilizes the replacement proxy auto-configuration file to configure itself to utilize the second proxy server on the LAN.
