Make page to tell browser not to cache preserve input values

Question

Most browsers cache form input values  So when the user refreshes a page  the inputs have the same values   Here s my problem  When a user clicks Save  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   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 Save again and gets an error message - even though the user thinks it s not  Which is irritating   This can be resolved by doing Ctrl   F5  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

From a Stack Overflow reference

It did not work with value="" if the browser already saves the value so you should add.

For an input tag there's the attribute autocomplete you can set:

<input type="text" autocomplete="off" />

You can use autocomplete for a form too.

Basically  there are two ways to clear the cache    lt form autocomplete  off  gt  lt  form gt    or      Textfiledid   attr  autocomplete    off

Are you explicitly setting the values as blank  For example    lt input type  text  name  textfield  value    gt    That should stop browsers putting data in where it shouldn t  Alternatively  you can add the autocomplete attribute to the form tag    lt form autocomplete  off      gt  lt  form gt

Another approach would be to reset the form using JavaScript right after the form in the HTML    lt form id  myForm  gt     lt input type  text  value    name  myTextInput    gt   lt  form gt    lt script type  text javascript  gt    document getElementById  myForm   reset     lt  script gt
