title: How make auto responder for specific requests
body: <p>I need in autoresponder. I develop flash application and I need substitution flash file from server to my local debug flash.</p>
  
  <p>I used Charles Proxy but in last week it became badly: internet connection very slow, some responses can't wait for request. </p>
  
  <p>Is there a same solution for this micro task? May be little extension for browser? Or can anybody create this extension for chrome or safari?</p>
  
  <p>Or Do you know why my Charles works slowly?</p>
