title: Does HTML understand "if-else"?
body: <p>Let's say I have Flash-version of and non-Flash version of my website. When a user comes to my website, is there any way to create the following logic:</p>
  
  <pre><code>if (user has flash-plugin installed) { load flash website }
  
  else { load non-flash website }
  </code></pre>
  
  <p>While we are here. Can I do the same for the bandwidth control? Let's say a Cable customer visits my websites. He has no problem loading my 10mb fully loaded flash website with background videos. But if someone with a slow internet connection visits my website, can I skip the Flash website and re-direct that user to non-Flash website?</p>
  
  <p>If there's no way to accomplish this, is there any workaround, any at all?</p>
  
  <p>Thanks in advance!</p>
