In ASP.NET , How can i retrieve a cookie value in the Session_End event of global.asax file ? The following code is throwing an exception "Object reference not set to an instance of an object"
string cookyval = "";
try
{
cookyval = Context.Request.Cookies["parentPageName"].Value;
}
catch (Exception ex)
{
cookyval = "";
}
Any advice ?

The Session_End event is fired by the IIS worker process, not an HTTP request. Therefore your HttpContext will be null and you won't be able to set a client's cookie.

Session_End isn't run in the context of a user request, so there's no access to cookies (or any other request variables).
If you put the value into Session, I think you can access that:
string cookyval = "";
try
{
cookyval = (string)Session["parentPageName"];
}
catch (Exception ex)
{
cookyval = "";
}
Otherwise, you'd need to write it to some other server side storage (like a database).

Not sure this is possible.
The request is no longer alive at the point the Session_End fires.
Sorry,
