Browser Caching: how to set Expires so a change is displayed if file is modified in the meantime?

    How do I set my htaccess file so that, when a file changes, that change is displayed when the file is viewed, despite Expires being set for a longer time?

    That is... I know I have to set for example: ExpiresDefault "access plus 1 month", but if the file changes in the meantime, that change is not visible.

    I don't understand why this isn't the case. In my own browser, unless I hit refresh, that change isn't visible.

    Should it be something of this sort? "modification plus 1 second" ?

    I understand there has to be a max-age, but if the file changes before it expires, how on Earth that change shouldn't be displayed?

    I have NOT found this specific question in here. Thanks a lot!
