You could implement your own controller factory, see here, and do whatever you like with the controller before you return it.

If all you need to do set is set a controller member variable then a quick and clean method is to override the controller's initialize method like so:

protected override void Initialize( RequestContext rc) {
    base.Initialize(rc);
    //Add any variable initialization here
    employeeId = rc.HttpContext.Request.Cookies["userid"]["emp_id"];
}
