I want to override the cookie path for ASP.NET using asp.net with c#. I tried setting the cookie with path pointing to the Virtual Application Directory.
I am able to point to the desired directory configured in config file but multiple cookies are getting generated

What I have tried:

Web.Config file
    <add key="UserDefiniedCookiePathFilter" value="/DDS_AHB"/>

Global.asax page
Under Application_PreSendRequestHeaders Event

string CookiePath= ConfigurationManager.AppSettings["UserDefiniedCookiePathFilter"];
            Response.AppendHeader("Set-Cookie", "path="+CookiePath);
