Re: how not to cache background image?

A simple solution is to add a parameter to the URL (ex. ?v=1 or ?<random_number>), and change the parameter value to force image reload. The parameter can be ignored by the server side, just used to force the image reload in the client side.

See http://stackoverflow.com/questions/1431512/is-there-a-way-to-force-browsers-to-refresh-download-images

Hello,

I set the background image of a web app in the root panel like this:

getElement().getStyle.setBackgroundImage(url);

When I change the background image, I only change a symbolic link on the server, so the url remains the same.

However, when I change it, the users still see the old image.

What can I do, so that the change will be visible immediately?

Thanks

Magnus
