1.jsp代码：

<%--
 Document : index
 Created on : 2009-10-4, 12:45:43
 Author : lucifer
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 <title>JSP Page</title>
 </head>
 <body>
 get Scheme:
 <%=request.getScheme()%>
 
 get PRotocol:
 <%=request.getProtocol()%>
 
 get Remote Address:
 <%=request.getRemoteAddr()%>
 
 get Remote Host:
 <%=request.getRemoteHost()%>
 
 get Server Name:
 <%=request.getServerName()%>
 
 get Server Port:
 <%=request.getServerPort()%>
 
 get Header:
 <%=request.getHeader("User-agent")%>
 
 get Method:
 <%=request.getMethod()%>
 
 get Request's URL:
 <%=request.getServletPath()%>
 
 get Request URI:
 <%=request.getRequestURI()%>
 
 get Request session ID:
 <%=request.getRequestedSessionId()%>
 </body>
</html>

2.输出：

get Scheme: http
get Protocol: HTTP/1.1
get Remote Address: 0:0:0:0:0:0:0:1
get Remote Host: 0:0:0:0:0:0:0:1
get Server Name: localhost
