Question

I use the following code to copy a certain line of text from the website listed.

    'Track A
    Dim TrackA As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("https://pilotweb.nas.faa.gov/common/nat.html")
    Dim GaA As System.Net.HttpWebResponse = TrackA.GetResponse
    Dim WrA As System.IO.StreamReader = New System.IO.StreamReader(GaA.GetResponseStream)
    Dim ContentStrA As String = WrA.ReadToEnd
    Dim StartIndexA As Integer = ContentStrA.IndexOf(vbLf & "A ") + 1
    Dim StrLengthA As Integer = ContentStrA.IndexOf(vbLf, StartIndexA) - StartIndexA

However when I open the link in a tab in VB, it shows a version of the site from a few days ago, how do I prevent this from happening as I need the current version of the site?

Change the Cache Policy of your System.Net.HttpWebRequest object, so that you're not getting cached results.

Alternatively, you can clear the cache for your URL.
