Howto Create a Hit Counter Using a Database in ASP.NET 1.x with C#

Published 17 years ago

If you have a live Web site on the World Wide Web, you may be interested in how many people are visiting your site. You can of course analyze the log files of your Web server but that information is usually difficult to read. The log files contain information for each and every request a visitor has made to your site, including resources like images, Flash movies and so on. This makes it near impossible to extract information about individual users. It would be a lot easier if you could count the number of individual users that have visited you since you started your site. It would also be useful if you could see the number of users that are currently browsing your site.

This article will show you how to accomplish these two tasks by storing the hit counters in shared variables in the Global class and in a database using code in the Global.asax file. The counters in the shared variables are used to display them on a page in your Web site; either as a counter so your visitors can see it as well, or somewhere on a page in your Admin section, so only you have access to them. By writing the counters to a database you can maintain their value even when you restart the Web server, while you still have a fast and scalable solution.

This article extends the ideas from two previous articles where the values of the counters were just stored in static variables in the Global class and in a text file.

There are also Classic ASP and VB.NET versions of this article available.

"Upgraded" to ASP.NET 2.0 a.k.a. Whidbey

Published 17 years ago

Today I installed an early alpha release of ASP.NET 2.0, also known as Whidbey on my server. Yeah, yeah, I know. I shouldn't install beta stuff on my production servers, but I just couldn't resist it. I guess I'll have to live with the consequences (I am typing this message directly from the SQL Server Enterprise Manager because my Login functionality broke down ;-) )
