How to avoid comparison without maintaining session?
<p>I have one web page, which displays the data which has been captured earlier. Now this data comes from database and belongs to multiples records of a database table.When user updates this data, we have to update our database records.Problem is I can not keep track of which records has been modified and since we don't have session. So I have fetch all the records again and compare with data from web page. If any one knows better ways of doing it(avoiding the comparison) please help me out.</p>
