title: Android (Samsung Galaxy Tab) limit domains (websites) that can be browsed - web filter
body: <p>Is it possible to limit websites (domains) that can be accessed from android tablet (in our case Samsung Galaxy Tab 2)? 
  I found out a couple of "web filter" apps but they all do the same thing - block adult/illegal websites. In our case I want to block everything except for one website.</p>
  
  <p>The purpose of this is to enable customers in our store to browse only the online catalog through the tablet (but would not be able to navigate to other pages).</p>
