好，下面开始从头讨论上面的代码。
< %@ LANGUAGE="VBSCRIPT" % >
< %
RequestName = Request.Form("Name")
RequestLeaveMeAlone = Request.Form("LeaveMeAlone")
If RequestName < >"" or RequestLeaveMeAlone < >"" then
Response.Cookies("MySiteVisitorName") = RequestName
Response.Cookies("MySiteVisitorName").Expires = #January 01, 2010#
Response.Cookies("MySiteLeaveMeAlone") = RequestLeaveMeAlone
Response.Cookies("MySiteLeaveMeAlone").Expires = #January 01, 2010#
End if
VisitorName = request.cookies("MySiteVisitorName")
LeaveMeAlone = request.cookies("MySiteLeaveMeAlone")
If VisitorName ="" and LeaveMeAlone ="" then
% >
< HTML > < HEAD > < /HEAD >
< body bgcolor="#ccffff" text="black" link="navy" vlink="purple" >
< DIV ALIGN="CENTER" >
< form action="index.asp" method="POST" >
< H2 >Let's be friends< /H2 >
What's your name (leave blank and hit the Submit button if you don't want us to know)?
< input type="text" name="name" >< BR >< BR >
< input type="hidden" name="LeaveMeAlone" value="x" >
< input type="submit" value="Submit" >
< /FORM >
< /DIV >
< /BODY >
< %
End if
If VisitorName < > "" then
Response.write "Hi, " & VisitorName & "! I hope you are having a great day!"
End if
'rest of the page
% >
好，现在来看看上面的代码实现执行了什么。首先，设置页面。然后，检查表单变量（在同一个页面中）。如果表单变量存在，就创建cookie，并设置到期时间。
< %@ LANGUAGE="VBSCRIPT" % >
< %
RequestName = Request.Form("Name")
RequestLeaveMeAlone = Request.Form("LeaveMeAlone")
If RequestName < >"" or RequestLeaveMeAlone < >"" then
Response.Cookies("MySiteVisitorName") = RequestName
Response.Cookies("MySiteVisitorName").Expires = #January 01, 2010#
Response.Cookies("MySiteLeaveMeAlone") = RequestLeaveMeAlone
Response.Cookies("MySiteLeaveMeAlone").Expires = #January 01, 2010#
End if
If VisitorName ="" and LeaveMeAlone ="" then
% >
< HTML >
< HEAD >
< /HEAD >
< body bgcolor="#ccffff" text="black" link="navy" vlink="purple" >
< DIV ALIGN="CENTER" >
< form action="index.asp" method="POST" >
< H2 >Let's be friends< /H2 >
What's your name (leave blank and hit the Submit button if you don't want us to know)?
< input type="text" name="name" >< br >< br >
< input type="hidden" name="LeaveMeAlone" value="x" >
< input type="submit" value="Submit" >
< /FORM >
< /DIV >
< /BODY >
< %
End if
如果cookie已经存在，并且用户名字存在，就显示给访问者一个欢迎界面，然后执行其余的代码。
If VisitorName < > "" then
Response.write "Hi, " & VisitorName & "! I hope you are having a great day!"
End if
'rest of the page
% >
尽管上面的这个例子很简单，但可以从中扩展许多富有创造力的应用。你可以在表单中加入许多功能，以便定制化web站点。你还可以让访问者定制网站的色彩、字体，以至于其他web元素。有可能的话，你可以询问访问者的生日，当访问者在那一天来访时，你就可以显示“生日快乐”的信息给他。
