I’m a complete noob to caching and to top it off, for reasons beyond my control, I cannot add/modify my response header sent from my servlet (ridiculous I know). Is there any other way I can tell the user’s browser to cache the images similar to a typical Last-Modified or Expires header? I’ve heard of ways of doing it in jquery but all I’ve seen is jquery image pre-loading which isn’t the same thing.
Changed my requests to call from a new servlet that I made so that I could modify/add headers so simply bypassed the issue I was having.
