title: Does 'cache: false' PREVENT caching, or UNIQUE-IFY the request to bypass cached?
body: <p>If I make multiple requests for a resource via ajax calls with 'cache: false', does this <em>prevent</em> the browser from caching each response using the request header (or some other way), or does it <em>bypass</em> the previously cached responses because the resource url is made unique due to the _=date param and thus never matches anything in the cache?</p>
  
  <p>As a reference, here is the jquery documentation on the ajax's cache property: '<em>If set to false, it will force requested pages not to be cached by the browser. Note: Setting cache to false will only work correctly with HEAD and GET requests. It works by appending "_={timestamp}" to the GET parameters.</em>'</p>
  
  <p>So does it really 'force requested pages not to be cached'? Or does it simply imitate that effect by appending the date - with the affect that no two requests are ever the same and so a fresh request made (but all the while the poor browser has a whole bunch of cached but never used responses)?</p>
  
  <p>(If I am so miss understanding the way caching works please feel free to school me!! (I'm assuming its basically a key value type of system with the key being the request information, and the value being the response for that request.))</p>
