A method and server system for exchanging data between a wireless electronic device and another computer system. This system allows a wireless electronic device to securely communicate with an Intranet by verifying authentication parameters. The first authentication parameter is the device serial number and a password which authenticates the network connection. The second authentication parameter is a user name and password that authenticates the user's access to applications on the Intranet. The system uniquely integrates the authentication parameters into every query the wireless device makes to the Intranet to maintain the session between the wireless device and the Intranet. Beneficially, the authentication parameters are not stored on any particular network device and do not burden either the server or the wireless device with maintaining the session. In another embodiment of the present invention, the server system uses a link rewriter service for examining web pages generated by applications of the Intranet to identify links that target any application that is resident on the Intranet. The link rewriter uses a look up table in a database to rewrite the link to include a keyword that designates the targeted application and its Intranet server. The keyword is then used to route links to the Intranet and if a link is not resident on the Intranet, the query will be routed to the Internet.
