如果HTTP客户端关闭连接Servlet怎么得到通知?
我指的是 *数据传输过程中* HTTP连接被客户端关闭。下面是我以前在tomcat-user@jak
arta.apache.org上的问题原文：
I notice that the following jsp is still running when the client terminates
his web browser:
<%
for(int i=0;i<100;i++){
try{
Thread.currentThread().sleep(2000);
System.out.println((i+1)+": Hello");
for(int j=0;j<1000;j++)
out.println("hello");
}
catch(Exception e){
System.out.println("Exception");
e.printStackTrace();
}
}
%>
So althougth the jsp/servlet can no more write any data to the
browser(which is terminated by the client),the jsp/servlet can still write
the the jsp output stream "out" without any exception thrown by the
"println" method,and the jsp/servlet is blind to the fact that it can no
more really write any thing to the client(the client can no more receive
the data),it keeps running util it finishes the "for" cycles,just as
nothing happens.
But I want to be notified when the HTTP connection is close by the web
client.How can I do that?
望各位大牛解答，感激不尽。
