Hi Friends,
In this article i will tell you how to count total number of visitors in website by using simple 3 steps
This is a very simple website user counter to see
how many people have visited a web page if you want to show it on a
web page.
Step 1:
We can do this by using (or creating) a global.asax file.
Every time a session is started, you increment an integer, which
holds the number of current visitors. Every time a session is ended, you
subtract one from that integer. Next, you will have to use public properties
for all pages to be able to retrieve the information.
public class Global : System.Web.HttpApplication
{
private static int totalNumberOfUsers = 0;
private static int currentNumberOfUsers = 0;
protected void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
totalNumberOfUsers = 0;
}
protected void Session_Start(Object sender,
EventArgs e)
{
// Code that runs when a new session is started
totalNumberOfUsers += 1;
currentNumberOfUsers += 1;
}
protected void Session_End(Object sender, EventArgs
e)
{
// Code that runs when a session ends.
// Note: The Session_End event is raised only when the
sessionstate mode
// is set to InProc in the
Web.config file.
//If session mode is set to StateServer
// or SQLServer, the event is not raised.
currentNumberOfUsers -= 1;
}
protected void Application_End(Object sender, EventArgs e)
{ }
public static int TotalNumberOfUsers{ get { return totalNumberOfUsers; } }
public static int CurrentNumberOfUsers{ get { return currentNumberOfUsers; } }
}
Step 2:
Next, in your control, set the values of the global.asax file in
the right labels.
private void Page_Load(object sender, System.EventArgs e)
{
int currentNumberOfUsers = HitCounters.Global.CurrentNumberOfUsers;
int totalNumberOfUsers = HitCounters.Global.TotalNumberOfUsers;
lblCurrentNumberOfUsers.Text = currentNumberOfUsers.ToString();
lblTotalNumberOfUsers.Text = totalNumberOfUsers.ToString();
}
Step 3:
In order for this to work correctly we need
to enable sessionstate and configure its
mode to InProc value (in our
web.config file):
<system.web>
<sessionState mode="InProc" cookieless="false" timeout="20" />
</system.web>
In-process mode stores session state values and variables in
memory on the local Web server.
It is the only mode that supports the Session_OnEnd event that we used previously.
Timeout value (in minutes, not in seconds) configures how long our sessions are kept 'alive' - in other words
here we set how long our users can be inactive before considered Offline.
In this example timeout is set to 20 minutes, so while our visitors click on some links in our website at least once
in a 20 minutes, they are considered online.
