How to resolve cookie path attribute mapped to root folder in ASP.NET

protected void Application_EndRequest(Object sender, EventArgs e)
       {
           // Iterate through any cookies found in the Response object.
           foreach (string cookieName in Response.Cookies.AllKeys)
           {
               Response.Cookies[cookieName].Secure = true;
               Response.Cookies[cookieName].Path = ConfigurationManager.AppSettings["UserDefiniedCookiePathFilter"];
           }
       }

how can i achieve this.is there any common code or any web config setting to set default path of cookie?

i want to do it from global.asax file.

protected void Application_EndRequest(Object sender, EventArgs e)
       {
           // Iterate through any cookies found in the Response object.
           foreach (string cookieName in Response.Cookies.AllKeys)
           {
               Response.Cookies[cookieName].Secure = true;
               Response.Cookies[cookieName].Path = ConfigurationManager.AppSettings["UserDefiniedCookiePathFilter"];
           }
       }
