title: iOS Cache Policy
body: <p>I am doing a connection to the NSURL and I need to create a request to bypass all the cache policy. I have seen examples such as :</p>
  
  <pre><code>NSURLRequest *request = [NSURLRequest requestWithURL:baseURL cachePolicy:0 timeoutInterval:10];
  self.urlConnection = [[[NSURLConnection alloc] initWithRequest:request delegate:self] autorelease];
  </code></pre>
  
  <p>May I ask what does the cache policy 0 refers to? Have tried searching for what the number represents but I'm not getting any answer I need. Thanks! :)</p>
