It's about making changes in design (css-files and images) on a website which is already online and in use. I wonder what is the best-practice to make sure that visitors see the changes without clearing there browser's cache manually. Things that came in my mind:
- change meta-tag - dismissed because I do not want the site to be ALWAYS loaded from the server
- include the css-file with a parameter (like timestamp) after made a change
- change the names of included images so that they are reloaded - means also change names in the files where images are included
- ?
What else could achieve the loading from server? Did I forget some advantages/disadvantages?
