I have web hosting at MediaTemple. By default, is it likely to be set up to tell the browser to cache the images and other assets that are served?
If not, how do I set up the caching? And then how would I be sure that it was working? Feel free to point me to a good newbie caching tutorial.
I don't want to serve the same images every time the user launches the game.
I'd like to set the the expiration date as long as possible. I'm fine with tacking a version number onto the filename when the asset changes.
I know this is a frightfully newbie question. I'm more comfortable with front-end programming than with server issues.
