title: Interception of AJAX interaction of UIWebView and WebServer
body: <p>i'm trying to make a web browser with custom encryption for iOS.</p>
  
  <p>For this i want to make a local proxy, which will implement crypt/encrypt logic of data, and interact with remote server.
  And i want UIWebView to work with this proxy, like with web server. </p>
  
  <p>The problem is ajax, where is a place to intercept UIWebView sending and receiving ajax requests and responses? How is it better to work with local proxy and xmlhttprequests?</p>
