title: OpenLayers - is (local) caching possible beyond the LocalStorage?
body: <p>There is a (standard) caching feature for OpenLayers via LocalStorage. The size of LocalStorage is per app max 10Mb. </p>
  
  <p>Is there a (standard or) easy way to cache tiles locally on the mobile so they can be used for offline presentation / navigation? In this way the caching could exceed the 10MB limit. </p>
  
  <p>If so, what are the disadvantages? </p>
