A Preliminary Study on listener and filter. 1. Implementation of Online users: Create a static variable onlinecounter. When a session is received, onlinecounter ++ and onlinecounter -- when the session is destroyed --. The listener class code is as follows: package com.dr; import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpSessionEvent;import javax.servlet.http.HttpSessionListener; import

This article mainly introduces the use of application object in ASP.net to achieve a simple online statistics function, this article gives the implementation steps and corresponding code examples, the need for friends can refer to the Note: Recently in review asp.net, in order to deepen the impression, will make some small demo program, share to everyone. 1 new asp.net web site, edit the Global.asax file,

Let's start with a new Access database Content is Table Name: Zai Word Field 1.ip 2.time Create a file for index.asp And then on the following program!

In the Global.asax.cs file, code:protected void Application_Start () { application["onlineusercount"] = 0; Arearegistration.registerallareas (); Registerglobalfilters (globalfilters.filters); RegisterRoutes (routetable.routes);} protected void Session_Start (object sender, EventArgs e) { application.lock (); application["Onlineusercount"] = Convert.ToInt32 (application["Onlineusercount"]) + 1; Application.UnLock ();} protected void Session_End (object sender, EventArgs e) {

Today, I want to show the number of people online in blog statistics. On the internet to find a lot of examples, not the database storage data is the file storage, the code seems too complex. After the evening came back, conceived the next, see my server installed Memcache service, why not use Memcache to achieve it. The following is the implementation process: ： Implementation code: 

Statistics | online | Number Like most of us topics, I ' m covering this one due to user demand for it. If you ' ve been to any one of a few dozen asp-based sites recently, you ' ve probably seen a example of the script we ' ve GoiNg to cover in this article. It ' s The little line at the top of these pages saying something like "There are users currently on this site!"It ' s sort of cute and it gives you t

Access | statistics | online | The program is a little bit difficult, because he is sending each picture separately, so it's not as big as a CGI-generated picture. And the pictures can be reused, so the rate is high speed. It just doesn't go without JavaScript.

When browsing the web, you can often see the number of "people on the current site is xxx" online count. How to use ASP to do one? First of all, the analysis of its practice, in general, these online statistics refers to the number of visitors in a period of time statistics. For example (within 5 minutes, 10 minutes) a

Php+mysql realize the number of online Web site, the background has MySQL database support. You can directly calculate the current number of online Web site. The first is to create a MySQL database table. CREATE TABLE TableName (field type (max_length) DEFAULT ' Default_value ' (not) NULL} The SQL statement that you can use. CREATE TABLE Useronline (timestamp int () DEFAULT ' 0 ' not NULL,IP varchar not

First, the session simple introduction in doing online statistics number listeners before, need to understand a brief session. Session is stored on the server side, generally placed in the server's memory (for high-speed access), Sessinon when the user accesses the first access to the server, you need to be aware that only access to the JSP, servlet and other programs will create sessions, access only HTML,
