An approach for providing mirror servers (101, 103) of a primary server (109) to enhance efficient retrieval of web information is disclosed. A primary server (109) communicates with one or more secondary servers (i.e., mirror servers) (101, 103); the primary server (109) and the secondary servers (101, 103) communicate with each other over a communication network (105), such as the public Internet. A user station (107) initially communicates with the primary server (109) to retrieve information. The primary server (109) determines a particular secondary server (101 or 103) based upon network analysis data. The network analysis data may optionally be stored as a cookie in the user station (107). Thereafter, the primary server (109) instructs the user station (107) to communicate with a particular secondary server (101 or 103) for subsequent requests. The secondary server (101 or 103) is selectively synchronized with the primary server (109).
