JS redirect ?

[sigepmest37]

The code i have so far:

<SCRIPT LANGUAGE=JavaScript1.1>
<!--
var MM_contentVersion = 7;
var plugin = (navigator.mimeTypes && navigator.mimeTypes["application/x-shockwave-flash"]) ? navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin : 0;
if ( plugin ) {
  var words = navigator.plugins["Shockwave Flash"].description.split(" ");
     for (var i = 0; i < words.length; ++i)
     {
  if (isNaN(parseInt(words[i])))
  continue;
  var MM_PluginVersion = words[i]; 
     }
 var MM_FlashCanPlay = MM_PluginVersion >= MM_contentVersion;
}
else if (navigator.userAgent && navigator.userAgent.indexOf("MSIE")>=0 
   && (navigator.appVersion.indexOf("Win") != -1)) {
 document.write('<SCR' + 'IPT LANGUAGE=VBScript\> \n'); //FS hide this from IE4.5 Mac by splitting the tag
 document.write('on error resume next \n');
 document.write('MM_FlashCanPlay = ( IsObject(CreateObject("ShockwaveFlash.ShockwaveFlash." & MM_contentVersion)))\n');
 document.write('</SCR' + 'IPT\> \n');
}
if ( MM_FlashCanPlay ) {
 window.location.replace("flashindex.html");
} else{
 window.location.replace("htmlindex.html");
}
//-->
</SCRIPT>

This detects if the user has the proper version of Flash Installed on their comp.

I would like to check the users bandwith before I run this check so that if they are on a low speed connection we can just bypass the flash check and send them to the html page. And if they have high speed we can perform the above check.

any suggestions?
