  1.   

    a.asp
    <html>
    <%@ Language=JScript %>
    <%
    if (Request("modify")=='y'){
    if (Request.Form("txt")=='123'){
    Response.Redirect ("b.asp")
    }else{
    Response.Redirect ("c.asp")
    }
    }
    %>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <meta name="GENERATOR" content="Microsoft FrontPage 4.0">
    <meta name="ProgId" content="FrontPage.Editor.Document">
    <title>New Page 1</title>
    </head><body><form name="frm1" method="POST" action="a.asp?modify=y">
      <p><input type="text" name="txt" size="20"></p>
      <p><input type="submit" value="提交" name="B1"><input type="reset" value="全部重写" name="B2"></p>
    </form></body></html>
    b.asp
    <html><head>
    <meta http-equiv="Content-Language" content="zh-cn">
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <meta name="GENERATOR" content="Microsoft FrontPage 4.0">
    <meta name="ProgId" content="FrontPage.Editor.Document">
    <title>b</title>
    </head><body><p>b.htm</p></body></html>
    c.asp
    <html><head>
    <meta http-equiv="Content-Language" content="zh-cn">
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <meta name="GENERATOR" content="Microsoft FrontPage 4.0">
    <meta name="ProgId" content="FrontPage.Editor.Document">
    <title>c</title>
    </head><body><p>c.htm</p></body></html>
    把三个页面放在一个文件夹内就行了，建一个虚拟目录，打开a.asp就行了
      

  2.   

    if(document.form1.text.value="123")
       location.href="a.html";
    location.href="c.html";
