Web Proxy Service
The first component of the Proxy Server is the Web Proxy service. This service is generally used directly with applications such as Internet Explorer, Netscape, Point Cast Network, and other CERN-compatible applications. This service offers the following support:
? Hypertext Transfer Protocol (HTTP) support and object caching
? File Transfer Protocol (FTP) support and object caching
? Gopher protocol support
? Disk caching
? IP address aggregation (using a single address for multiple computers)
? IP address translation
? CERN-proxy compatibility
? SSL (HTTPS and SNEWS) tunneling (data encryption)
? Integrated, user-level security providingencrypted logon for browsers, which supports Windows NT Challenge/Response authentication
? Support for most operating systems including UNIX, Windows NT Server, Windows NT Workstation, Windows 95, Windows for Workgroups, Windows 3.1, and Macintoshsystems
? Masks LAN structure, topology, addressing, and so on
? Logging of Internet requests from clients
? Management of multiple servers through a single common GUI interface
? No direct Internet access to the LAN or vice versa. The Proxy Server performs all operations
The above is how the web proxy is structually designed in MS proxy server. The short answer is... it will work... you have to input the settings in the browser configuration...
