您可以像这样来循环遍历所有的服务器变量：

<%

for each x in Request.ServerVariables

response.write(x & " ")

next

%>

下面的实例演示了如何查明访问者浏览器的类型、IP 地址等等：

<html>

<body>



You are browsing this site with:

<%Response.Write(Request.ServerVariables("http_user_agent"))%>





Your IP address is:

<%Response.Write(Request.ServerVariables("remote_addr"))%>





The DNS lookup of the IP address is:

<%Response.Write(Request.ServerVariables("remote_host"))%>





The method used to call the page:

<%Response.Write(Request.ServerVariables("request_method"))%>





The server's domain name:

<%Response.Write(Request.ServerVariables("server_name"))%>





The server's port:

<%Response.Write(Request.ServerVariables("server_port"))%>





The server's software:

<%Response.Write(Request.ServerVariables("server_software"))%>
