I think that you can do a VaryByCustom="scheme" and add this to your Global.asax.cs file (inlcuding a couple other others that I use as well app version & user):

    public override string GetVaryByCustomString(HttpContext context, string custom)
    {
        if (custom.Equals("version", StringComparison.CurrentCultureIgnoreCase))
        {
            Assembly asm = Assembly.GetExecutingAssembly();
            string[] parts = asm.FullName.Split(',');
            string version = parts[1].Trim().ToLower();
            return version;
        }
        else if (custom.Equals("user", StringComparison.CurrentCultureIgnoreCase))
        {
            var user = Membership.Users.CurrentUser;
            return null == user ? string.Empty : user.Id.ToString();
        }
        else if (custom.Equals("scheme", StringComparison.CurrentCultureIgnoreCase))
        {
            var scheme = context.Request.IsSecureConnection ? "https" : "http";
            return scheme;
        }
        else
            return base.GetVaryByCustomString(context, custom);
    }
