title: Make page to tell browser not to cache/preserve input values
body: <p>Most browsers cache form input values. So when the user refreshes a page, the inputs have the same values.</p>
  
  <p>Here's my problem. When a user clicks <em>Save</em>, the server validates POSTed data (e.g. checked products), and if not valid, sends it back to the browser. However, as stated above, even if the server clears selection for some values, they may still be selected because of the browser cache!</p>
  
  <p>My data has invisible (until parent item selected) checkboxes, so the user may be even not aware that some previous value is still selected, until clicking <em>Save</em> again and gets an error message - even though the user thinks it's not. Which is irritating.</p>
  
  <p>This can be resolved by doing <kbd>Ctrl</kbd> + <kbd>F5</kbd>, but it's not even a solution. Is there an automatic/programmatic way to tell browser not to cache form input data on some form/page?</p>
