Crystal Reports :: Crossing Sessions / Not Working On Multiple Machines

I wrote a crystal web server using asp.net security. i have multibple reports in a few different directories, and i have a report viewer form in each secured directory. when i load a particlular report on one machine's web browser, if i go to another machine and launch that report, the report instantly shows up with the parameters selected from the other machine. it's like after the report launches, the next request for that report just dishes out the previously built page.

I have not experienced this before, and makes my report site kinda useless. why these reports aren't treated as separate sessions?

*here is the markup for the frmReportViewer.aspx page:*
<form id="form1" runat="server">
<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server"
AutoDataBind="true" BestFitPage="False" Width="1100" Height="680"
ReportSourceID="CrystalReportSource1" BorderColor="#000099"
BorderStyle="Inset" PrintMode="ActiveX" />
<CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
<Report FileName=""
</Report>
</CR:CrystalReportSource>
</form>

*here is the vb code for the frmReportViewer.aspx page:*

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.CrystalReportViewer1.HasCrystalLogo = False
If Not IsPostBack Then
ReportName = Request.QueryString("reportname") & ".rpt"
Me.CrystalReportSource1.Report.FileName = ReportName
DBConnectionForReports(CrystalReportSource1.ReportDocument)
End If
end sub
Public Function DBConnectionForReports(ByRef rpt As ReportDocument) As Boolean
Dim logonInfo As New TableLogOnInfo
'Dim table As System.Web.UI.WebControls.Table
Dim srptServer As String
Dim srptUN As String
Dim srptPass As String
Dim crConnInfo As New ConnectionInfo
Dim subRepDoc As New ReportDocument
Dim table As Table
For Each table In rpt.Database.Tables
srptServer = "calp"
srptUN = "cdiappsro"
srptPass = System.Configuration.ConfigurationManager.AppSettings.Item("OraclePassword").ToString
logonInfo = table.LogOnInfo
logonInfo.ConnectionInfo.ServerName = srptServer
logonInfo.ConnectionInfo.UserID = srptUN
logonInfo.ConnectionInfo.Password = srptPass
logonInfo.TableName = table.Name
table.ApplyLogOnInfo(logonInfo)
Next table
End Function
