As a web developer web browser caches are annoying because I often want to see the current state of the page on the server.
To disable Google Chrome’s Cache copy and paste the following into terminal on your Mac:
chmod 222 ~/Library/Caches/Google/Chrome/Default/Cache/index
chmod 222 ~/Library/Caches/Google/Chrome/Default/Media\ Cache/index
Click Here to Test but don’t clear any cache just reload the page without using the refresh button.
