怎样配置IIS既可以运行ASP又可以运行PHP_ASP教程

以下为引用的内容：

<script type="text/javascript">
function bdmp3Url(){
    this.I=[];
    this.E=[];
    this.init();
}
bdmp3Url.prototype = {
    init:function(){
        this.getkeys(0,9,48);
        this.getkeys(10,35,55);
        this.getkeys(36,61,61);
    },
    getkeys:function(Q,N,O){
        for(var P=Q;P<=N;P++){
            this.I[P]=String.fromCharCode(P+O);this.E[P+O]=P;
        }
    },
    code:function(C,D,F){
        //偏移量
        var K=D%26;K=K?K:1;K=C?K:-K;
   
        var N=F.length,I=this.I,E=this.E,R='',Q='';

        for(var P=0;P<N;P++){
            R=F.charAt(P);
            if(/[A-Za-z0-9]/.test(R)){
                var S=E[F.charCodeAt(P)]+K;
                if(C){
                    if(S>61){S-=62;}
                }else{
                    if(S<0){S+=62;}
                }
                R=I[S];
            }
            Q+=R;
        }
        return Q;
    }
}

var x = new bdmp3Url();

document.write(x.code(1,1227148832,'http://www.wzms.net/UploadFiles/2007-1/115747297.wma')+'<br/>');
