I am enhancing a testing tool to send some hits against a Web server. The code initializes two instances of the class:

    Private oInternet As Framework.Internet = Nothing
    Private oInternet2 As Framework.Internet = Nothing

In the form Load() event, I have this:

        oInternet = New Framework.Internet(oApp)
        oInternet2 = New Framework.Internet(oApp)

Then, in a button of the form, I am issuing the startup of two timers where they each have a timer event including something like this:

        ' Get the URL
        oInternet.cUrl = LoadTestUrl.Text
        If Not oInternet.GetUrl() Then
        End If

        ' Get the URL
        oInternet2.cUrl = LoadTestUrl2.Text
        If Not oInternet2.GetUrl() Then
        End If

In the Internet class, I have something like this (simplified here just for the basis of explaining the situation):

    Public cHTML As String = ""
    Public oCookieContainer As System.Net.CookieContainer = New System.Net.CookieContainer

    ' Get the HTML response from a server
    Public Function GetUrl() As Boolean
        Dim lcUrl As System.Uri = Nothing
        Dim llSuccess As Boolean = False
        Dim loHttpWebRequest As System.Net.HttpWebRequest = Nothing
        Dim loStream As System.IO.Stream = Nothing
        Dim loString As System.IO.StreamReader = Nothing
        Dim loWebResponse As System.Net.WebResponse = Nothing

        ' Reset the values
        cHTML = ""

        ' Make it into a Uri
        lcUrl = New System.Uri(cUrl)

        ' Make it into a Web request
        loHttpWebRequest = System.Net.HttpWebRequest.Create(lcUrl)

        ' Assign the cookie container
        loHttpWebRequest.CookieContainer = oCookieContainer

        Try
            loWebResponse = loHttpWebRequest.GetResponse()
            loStream = loWebResponse.GetResponseStream()
            loString = New System.IO.StreamReader(loStream)
            cHTML = loString.ReadToEnd()
            llSuccess = True
        Catch loError As Exception
            cMessage = loError.Message
        End Try

        Return llSuccess
    End Function

If I only use one timer, thus sending only one URL in sequence, this works. As soon as I use two timers, they collapse on each other. Those are two instances of the class. Anyone knows why they would collapse on each other?
