六、HTTPServletRequest其他方法

//得到请求头中的信息
Enumeration<String> en = req.getHeaderNames();
while(en.hasMoreElements()) {
	String name = en.nextElement();
	out.print(name+":"+req.getHeader(name)+"<br/>");
}
		
		
System.out.println("context:"+req.getContextPath());
System.out.println("uri:"+req.getRequestURI());
System.out.println("url:"+req.getRequestURL());
System.out.println("Host:"+req.getRemoteHost());
System.out.println("ip:"+req.getRemoteAddr());

详情略。。。。。
