I am keep seeing the old images that are referenced in CSS file. This image was changed more than two months ago. The only way to refresh the images is to open the store via incognito mode.
I thought it might be related to .htaccess file, however in .htaccess file it is set to expire the css file after 7 days and png image after 30 days.
ExpiresActive On ExpiresByType image/png "access plus 2592000 seconds" ExpiresByType text/css "access plus 604800 seconds"
In my CSS file I have an image path as below:
The "newsletter.png" in css will never change. It's the actual file on the server that get replaced with new png file.
Is there a way I could refresh this from the server side, so all the clients who are browsing the store get to see the latest visuals?
