title: How to prevent the browser from caching a json file
body: <p>So I'm making this little project and I'm having some troubles with catching. One thing that's not working is the browser keeps caching the json file that contains save data and when I update the json somewhere else, the browser goes back to the old version of the json file that it has cached and reads off that. Unfortunately I dont want that. I dont want the browser to cache the file at all so that every time it loads up the page, it'll ask the server for the json file and act according to that file instead of whatever file that it has cached. I would however like to be able to cache all the other stuff that's on the page but if that has to be sacrificed for this to work then it's a sacrifice I'm willing to make. I'm envisioning that in JavaScript that there would be a call that says discard the current json file and go ask the server again for it or something like</p>
  
  <pre><code>&lt;script src="mySaveFiles.json" cache="no"&gt; 
  </code></pre>
  
  <p>or something of the sort to help me achieve what I'm talking about... help?</p>
