--%>
<%@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:

<br>
get server port:
<%=request.getserverport()%>
<br>

<%=request.getheader("user-agent")%>
<br>
