A Mechanism to Indicate Revisited Pages Whose Contents are Unmodified Since the Last User Visit Disclosed is a method to mark web pages as unchanged since last visit using the user's history list for browsing. With the explosion in Web content there is a tremendous number of links that people navigate through in their daily lives. It has, therefore, become very difficult to keep track of pages of interest, especially figuring out their change history. In general, it is the case that people tend to revisit pages they are acquainted with. This is presumably because they have some interest in the subject or there is something in the content they find appealing. So it makes sense to revisit those pages whose content one can trust. However, the content of many pages do not change very frequently. One often wastes a lot of time looking at the content trying to figure out whether the content has changed since the last visit. It has become very difficult to detect/quantify change histories of pages since the last invocation as the modifications are often only a minute (but it may still be something of interest to a particular user). It is clearly a waste of time trying to detect page modifications since last visit. Therefore, we try to address the following problem: How to detect if a page has changed since the last time it was visited?
