Abstract: A computer-based system and method for customizing navigation through a Web site based upon values of user information received from either an external or internal Web site upon entering the customized Web site. The Web site customization includes both customized navigation and functionality. Users are directed through the Web site in a streamlined manner, and information entered in the external or internal Web site is pre-populated so the user does not have to re-enter information already given. The Web site also customizes the navigation and functionality available to the particular user based on the information entered and on the entry point, therefore bypassing any unnecessary displays and avoiding redundancy.
