實(shí)例

您可以像這樣來循環(huán)遍歷所有的服務(wù)器變量：

<%
for each x in request.servervariables
response.write(x & "
")
next
%>

下面的實(shí)例演示了如何查明訪問者瀏覽器的類型、ip 地址等等：

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"))%>
