Execute method in global.asax every few minutes

What is the most effective way to execute a method in the Global.asax file every x number of minutes? Is there a way to have the ASP.NET server run a background thread that fires a tick event after a certain elapsed period?

Method 1

You could have a timer in the Application_Start of the Global.asax, but this is not very flexible since you need to do a request to the application for the timer to start. There are dangers to doing it this way though, as detailed by Haacked:

A better way of doing it is to have a web service that acts as an interface to your ASP.NET application and have a windows service that calls your web service on scheduled intervals:

Method 2

you could use combination of HTTPModule and ASP.NET TIMER to do this

(or)

You could use AJAX Timer control .

Method 3

Put a System.Timers.Timer object in Application_Start () in Global.asax.
