The present method for selective web caching comprises the steps of generating a table, the table comprising a URL, a time of last access and a time stamp of a web page, the table further comprising a URL, time of last access and time stamp of elements found on the web page; when a request for a web page is made, checking the requested web page's URL and time stamp and URL and time stamp of the requested web page's corresponding elements with the URL and time stamp listed in the table to determine whether any modification has been made; and selectively downloading in a cache only those elements which are deemed to have been modified.
