RSS Feed or Page Update

Is there a way to check if a site had a page update or a new post easily?? Even just to check if something had changed on the page. Any help would be appreciated.

Here is my code so far

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ListBox1.Items.Add(TextBox1.Text)
        Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(TextBox1.Text)
        Dim response As System.Net.HttpWebResponse = request.GetResponse()

        Dim sr As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())

        Dim sourcecode As String = sr.ReadToEnd()
        My.Settings.s1 = sourcecode
        My.Settings.s2 = sourcecode
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(TextBox1.Text)
        Dim response As System.Net.HttpWebResponse = request.GetResponse()

        Dim sr As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())

        Dim sourcecode As String = sr.ReadToEnd()
        My.Settings.s1 = sourcecode
        If (My.Settings.s1 <> My.Settings.s2) Then
            ListBox2.Items.Add(TextBox1.Text + "    NEW")
        End If

    End Sub

I check the pages html agents its original and if there diferent say new but it always comes up as diferent(NEW) and if its a php page (i think thats the problem) it does not work?
Edit: It seems to work when im using localhost so what would be the best thing to check if a website has had a new post or changed?

 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ListBox1.Items.Add(TextBox1.Text)
        Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(TextBox1.Text)
        Dim response As System.Net.HttpWebResponse = request.GetResponse()

        Dim sr As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())

        Dim sourcecode As String = sr.ReadToEnd()
        If (CheckBox1.Checked = True) Then
            My.Settings.s1 = sourcecode
            My.Settings.s2 = sourcecode
        End If
        If (CheckBox2.Checked = True) Then
            My.Settings.s3 = sourcecode
            My.Settings.s4 = sourcecode
        End If
        If (CheckBox3.Checked = True) Then
            My.Settings.s5 = sourcecode
            My.Settings.s6 = sourcecode
        End If
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Label3.Text = "Checking..."
        Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(ListBox1.SelectedItem)
        Dim response As System.Net.HttpWebResponse = request.GetResponse()

        Dim sr As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())

        Dim sourcecode As String = sr.ReadToEnd()
        My.Settings.s1 = sourcecode
        If (My.Settings.s1 <> My.Settings.s2) Then
            ListBox2.Items.Add(ListBox1.SelectedItem)
        End If
        If (My.Settings.s3 <> My.Settings.s4) Then
            ListBox2.Items.Add(ListBox1.SelectedItem)
        End If
        If (My.Settings.s5 <> My.Settings.s6) Then
            ListBox2.Items.Add(ListBox1.SelectedItem)
        End If
        Label3.Text = "Done"
    End Sub
