By default, the click handlers are invoked by ASP.Net (they depend on ViewState), and cannot be called externally unless changes are made to the code.

If you can modify the code within abctest.aspx, then it can be done by handling the POST. A rough example pasted below:

protected void Page_Load(object sender, EventArgs e)
{
    //Treat curl's POST method, but ignore the regular POST, as it will be handled by ASP.NET
    if (Request.HttpMethod == "POST" & !IsPostBack)
    {
        username.Text = Request["username"];
        password.Text = Request["password"];
        btnLogin_Click(this, null);
    }
}

protected void btnLogin_Click(object sender, EventArgs e)
{
    Response.Write("Success");
    //
}
