Disclosed is a method for a user of a web browser to use expiration dates contained within an HTML document to selectively remove items during web browser initialization from the browser's history, bookmarks, and local cache. These expiration dates allow the web browser to better control it's actions and the space it uses within a local file system where the browser is running. When a web browser down loads a web page, the web page could contain an expiration date for the document contents which indicates when the cached version of the web page is no longer valid and the browser should go back to the web to get a new version of the web page. On browser initialization any cached entries that have reached there expiration dates would be removed from the local browser cache thus freeing up space in the local file system. When the web browser down loads a web page, the web page could contain a history expiration date which signifies when the history element would no longer be valid. On browser initialization those history elements that are no longer valid based on expiration date would be removed from the web browsers history file. When the web browser down loads a web page, the web page could contain an expiration date for the URL address itself, which signifies when the web page will no longer be available on the web. When a URL with an expiration data is added to the book marks files it would be added specifying the expiration date contained in the URL. On browser initialization the browser would delete any bookmarks which have exceeded the URL address expiration data.
