GMS provides a simple caching Web proxy server. This allows GMS to sit on an office Internet gateway and provide users’ two most important requirements, delivery of Web pages and e-mail. This is ideal for use in a dial-up system. The caching facility helps reduce your bandwidth requirements by storing copies of frequently accessed files locally.
By integrating the proxy directly in to the GMS, it speeds up access and makes the proxy easy to use. For dial-up users, the combination of email server and proxy enables a reduction of online time by combining two actions (retrieving email and webpages) into a single action.
