    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()%>
        <br>
        get PRotocol:
        <%=request.getProtocol()%>
        <br>
        get Remote Address:
        <%=request.getRemoteAddr()%>
        <br>
        get Remote Host:
        <%=request.getRemoteHost()%>
        <br>
        get Server Name:
        <%=request.getServerName()%>
        <br>
        get Server Port:
        <%=request.getServerPort()%>
        <br>
        get Header:
        <%=request.getHeader("User-agent")%>
        <br>
        get Method:
        <%=request.getMethod()%>
        <br>
        get Request's URL:
        <%=request.getServletPath()%>
