Abstract
A solution is presented to keep track of the URLs that have been visited within an HTML file, identify the location or exit point of the last line that was displayed on a screen in a multi-screen HTML file, and return to the exact exit point location upon reentry to the web page by computing which section of the HTML file to display on the screen, and then displaying this section. The identification of whether a web page has changed after it has been visited by a user is also presented. A cyclic redundancy check is performed, comparing the current cyclic redundancy number with the last cyclic redundancy number obtained when the screen of exited multi-screen HTML file was last visited. If the web page has changed, the user has the option of viewing the web page at the top screen or going to the screen that contains the last exit position of the HTML file that was previously viewed.
