  Manifest File
  - It is a simple text file, which tells the browser what to cache (and what to never cache).
  
  - This file has three sections:
  
  1. CACHE MANIFEST
  - Files listed under this header will be cached after they are downloaded for the first time
  - The first line of this file is required:
  
  CACHE MANIFEST
  /theme.css
  /logo.gif
  /main.js
  
  - This file lists three resources: a CSS file, a GIF image, and a JavaScript file.
  - When this file is loaded, the browser will download the three files from the root directory of the web site.
  - Whenever the user is not connected to the internet, the resources will still be available.
  
  2. NETWORK
  - Files listed under this header require a connection to the server, and will never be cached
  - It specifies that the file "login.asp" should never be cached, and will not be available offline:
  
  NETWORK:
  login.asp
  - An asterisk is used to indicate that all other resources/files require an internet connection:
  
  NETWORK:
  *
  
  3. FALLBACK
  - The files listed under this header specifies fallback pages if a page is inaccessible
  
  - It specifies that "offline.html" will be served in place of all files in the /html/ catalog, in case an internet connection cannot be established:
  FALLBACK:
  /html/ /offline.html
