c# - Singleton WebService (ASMX, not WCF) -

Is there any way to define C # ASMX webserver as singleton? Maybe in web.config file? Currently I am not using WCF.

Thank you in advance

  [WebServices (namespace = "http://www.mydomain.eu/")] [WebServiceBinding (Confafoto = WsiProfiles.BasicProfile1_1)] [ System.ComponentModel.ToolboxItem (wrong)] Public class MyService: System.Web.Services.WebService {...}    
 
 
 You can not create a  web service, because the web service runs on IIS and it is considered as a web app and it is maintained in this way . Each customer will share a single application example, but each will have their own request, feedback, session etc.
