How can I force the web browser to reload a newly deployed Flash file without clearing the cache?

When I deploy a new .swf file in an HTML file as shown below, I have to clear the browser cache before the new .swf file loads in the browser. Is there anyway to force the browser to load the .swf file when I replace it with a new one on the server.

<embed type="application/x-shockwave-flash" wmode="transparent" pluginspage="http://www.adobe.com/go/getflashplayer" allowscriptaccess="sameDomain" name="Prototype" bgcolor="#869ca7" quality="high" id="Prototype" src="/flex/Prototype.swf">

Thanks, Chirag

Just append a number within the query string (you might think of it as version number of sorts). Then change that number whenever you change your SWF. When the number changes, the browser will see it as a different URL, so it'll skip the cache and go back to the server for a fresh copy of the swf.

<embed 
   type="application/x-shockwave-flash" 
   wmode="transparent" pluginspage="http://www.adobe.com/go/getflashplayer" 
   allowscriptaccess="sameDomain" name="Prototype" bgcolor="#869ca7" 
   quality="high" id="Prototype" src="/flex/Prototype.swf?1234" >
