    this.ver=navigator.appVersion

    this.agent=navigator.userAgent

    this.dom=document.getElementById?1:0

    this.opera5=this.agent.indexOf("Opera 5")>-1

    this.ie5=(this.ver.indexOf("MSIE 5")>-1 && this.dom && !this.opera5)?1:0; 

    this.ie6=(this.ver.indexOf("MSIE 6")>-1 && this.dom && !this.opera5)?1:0;

    this.ie4=(document.all && !this.dom && !this.opera5)?1:0;

    this.ie=this.ie4||this.ie5||this.ie6

    this.mac=this.agent.indexOf("Mac")>-1

    this.ns6=(this.dom && parseInt(this.ver) >= 5) ?1:0; 

    this.ns4=(document.layers && !this.dom)?1:0;

    this.bw=(this.ie6 || this.ie5 || this.ie4 || this.ns4 || this.ns6 || this.opera5)

    return this

The page showed up this:

The server is too busy at the moment. Please try again later.

..and maybe you should try editing this:

    this.ie=this.ie4||this.ie5||this.ie6

to this:

    this.ie=this.ie4||this.ie5||this.ie6 || this.ie7

and add this bellow IE6:

    this.ie7=(this.ver.indexOf("MSIE 7")>-1 && this.dom && !this.opera5)?1:0;
