What methods can I use to track the number of active visitors on my asp.net website?

I am seeking a more accurate way to track the number of current visitors to my asp.net website. While I am familiar with the common technique of creating an application variable and increasing it at session start, this method tends to inflate the numbers by counting requests from web crawlers, robots, and other spammer servers.

What I truly desire is a system that can differentiate between active human users who have opened up a browser (whether on mobile or desktop) to view my site, even if they are simultaneously browsing other websites in different tabs or windows. Essentially, I want a mechanism like an ajax hidden request generator that sends a signal to the server each time a visitor's browser has my site open.

Thank you for your assistance.

Answer №1

To determine if a request is from a search engine crawler, you can check the user-agent of the request using Request.Browser.Crawler. This will return true if the browser is identified as a crawler.

In addition to this method, you could also incorporate a javascript call to update the visitor count on a page. By combining these techniques, you can ensure that visitor counts are only updated for real users. It is important to verify that the request is not from a crawler when increasing or decreasing the user count. For example:

//increase the user count
if (Request.Browser.Crawler == false)
{
    Application["user_count"] = +1;
}

//decrease the user count
if (Request.Browser.Crawler == false)
{
    Application["user_count"] = -1;
}

Another approach is to utilize the Session_End and Session_Start events in the global.asax file of the application to handle these actions.

Answer №2

Storing data using the Application is a viable option, especially in the initial phases of your website or web application. However, it's important to address potential issues related to accessing multiple instances of the application state when the site is being loaded.
