By default, the ASP. NET MVC site dynamically adds the currently used ASP. Version number in the HTTP response header (Response header). If you use the Fiddler Web Debugger tool to view the HTTP wrapper package that is connected to an ASP. NET MVC Web site, you can see a "x-aspnetmvc-version" HTTP header in the response header. The version of ASP. NET MVC that is currently in use.
For security reasons, when you want to hide the version number sent by ASP. NET MVC, add the following code in the Application_Start () method of the Global.asax file to hide the version number in the HTTP header.
protected void Application_Start () { //hides the version information of ASP. NET MVC so that it does not appear in the HTTP header. Mvchandler.disablemvcresponseheader = true; Arearegistration.registerallareas (); Registerglobalfilters (globalfilters.filters); RegisterRoutes (routetable.routes);}
