Question

I have the next problem: I need to process only 1 request at a time from each user. Lets assume that server identifies each user be UserID, sent in query string. How can make the server work the way like FIFO (do not start processing next request until the previous is fully processed)? Should I use the named mutexes inside HTTP handler and assign the name to mutex by UserID?

Thanks in advance, Valentin

在提出第一项请求时,在届会期间树立了旗帜。只有在处理第一份请求后,才重开这一国旗。

如果用户再次提出要求,而没有完成第一项请求,就只是拒绝这一请求,即在没有执行任何进一步法典的情况下从程序要求中返回。此外,你还可以以适当的状况回答用户。

        public void ProcessRequest(HttpContext context)
        {
            context.Response.Write("<h1><b>HttpHandler Test</b></h1>");
            context.Session["Test"] = "Invoke a session in HttpHandler.";
            context.Response.Write(context.Session["Test"]+"<br>");
            context.Response.Write("<a href= HttpHandlerCsharp.aspx ><b>return</b></a>");
        }
    }
}
