title: Redirect all requests to another url
body: <p>I have sip application on my iPhone. It uses sip.server.com url to send requests and get responces.</p>
  
  <p>How can I redirect all request (<strong>not only http</strong>) from my domen to sip.server.com and then all responces from sip.server.com redirect to the application on iPhone.</p>
  
  <p>So I want to write my own domen instead of sip.server.com in the iPhone application.</p>
  
  <p>Is it possible with asp.net? </p>
