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!
