title: Is meteor keeping cache for each "publish"
body: <p>I'm using Iron Router (with RouteControllers) and I'd like to know if meteor keep cache for "publishes" when page (url) change.</p>
  
  <p>Example :
  I want use meteor for a cooking site, so I've a section with a BIG list of recipes, and I can filter this list (by theme, preparation time, etc.). So, potentially, there will be a lot of different lists.</p>
  
  <p>(This is a use case but my question can be valid for classic schema : a user visits a recipe detail page, and go away... does meteor clean cache for this subscription on server (which published the recipe datas) ?)</p>
  
  <p>If I use subscriptions, does meteor keep cache when I change filter information ? And if not, how to do that without keep cache on local user database (and on server) for each request use can make ?</p>
  
  <p>Sorry, I'm a beginner in meteor and it's a little confused for me. When I read documentation about meteor and publish/subscribes, I think that my app usage will increase memory excessively...</p>
