body: <p>How to clear the cache of a UIWebView?</p>
  
  <p>I am making a simple application (with only three buttons (back, forward, refresh) and a UIWebView) and I realized that in my Documents &amp; Data iPhone gets a very high value of Cache. I already looked at various documents and posts (even here at StackOverflow) but none solved the problem.
  If you need lines of codes, ask.</p>
