title: What are the options to listen to http traffic from the flash program embedded into a web-page?
body: <p>Here is my situation in a nutshell: there is a flash program built and it's being embedded into different site pages. There is no ability to change the flash program and I want a small add-on (let's name it add-on) so it would extend the functionality of the flash program a little bit. Example: my flash program asks for a quote from the main server, I need to display some additional information regarding the quote requested.</p>
  
  <p>The data is being returned by my server json-serialized and I can add any data to it, but as the flash program does not display additional information, I'd like it to show in a window, in a widget on the page or something alike.</p>
  
  <p>Prerequisites:
  a) Windows OS
  b) Http traffic (req/resp) should be read as is by the addon and the addon will make necessary calculations/actions and (probably) additional requests if needed
  c) The ability to show calculated results in any way so the end user could see
  d) Preferably the add-on should be invoked only when certain requests are fired (for example <a href="http://url/get/quote/1234" rel="nofollow">http://url/get/quote/1234</a>)
  e) I'd prefer not doing any extra requests; getting extra data from http response being fetched by flash program is fine with me.</p>
  
  <p>The options I believe are:</p>
  
  <ol>
  <li>Greasemonkey script. Does not work as probably it can not read http traffic unless it's the main page url.</li>
  <li>Firefox/Chrome addons. I read that Chrome forbids accessing the http requests, and I can not find any <a href="http://code.google.com/chrome/extensions/api_index.html" rel="nofollow">API methods</a> for watching the http traffic. but I'm not sure about <a href="https://addons.mozilla.org/en-US/developers/docs/reference" rel="nofollow">Firefox API</a>.</li>
  <li>Any other way?</li>
