There are two mechanisms for this:

 - <html manifest="">, which lists all the files needed by the app when 
   running offline

 - implementing HTML natively, and then downloading all the files linked 
   using explicit features like <script src=""> or links that are marked 
   as "external resource links".

Neither system is foolproof, though.
