Information retrieval and consumption from the web is becoming the fundamental way we manage our lives, business and leisure. To simplify retrieving information of our interest, a lot of research has been done in the area of web crawlers, or "bots" that navigate the web automatically, read web pages, and index those web pages based on the content of web pages. Another group of utilities that monitor web page changes have also emerged. Web crawlers provide very little control to the users in the manner in which the web is navigated and they fail to work with links that have links embedded in scripts. The web page monitoring applications fail when the pages are dynamically generated, and the links to the pages change all the time. Furthermore more and more content is being protected by authentication schemes such as username and password based authentication. These issues make the conventional web navigation automation tools ineffective for most useful applications. This innovation deals with these issues by providing interactive approach to learn the navigation and then repeat the learn sequence of actions, while monitoring for the changes in the values.
