I have a crystal report that is opened via a web application using vb.net 2005.  The problem we are seeing is that occasionally if a user has a session open and a new user initiates a session.  The second user will get the report with the first users information.  Does anyone know why this would happen? My code is shown below

Try
                oRep = New ReportDocument
                Response.Clear()
                Response.Charset = ""
                Response.ClearContent()
                Response.ClearHeaders()
                Response.ContentType = "application/pdf"
                ExportDirectory = New ExportOptions

                oRep.Load(strPath)
                oRep.SetDatabaseLogon("XXX", "XXXX")
                oRep.Refresh()
                oRep.SetParameterValue("@VAR1", VAR1)
                oRep.SetParameterValue("@VAR2", VAR2)
                oRep.SetParameterValue("@VAR3", VAR3)

                ExportDirectory = oRep.ExportOptions
                ExportDirectory.ExportFormatType = ExportFormatType.PortableDocFormat
                oRep.ExportToHttpResponse(ExportDirectory, Response, False, "rpt1")
            Else
                Err.Raise("6754")
                Err.Description = ("data elements not passed")
            End If
        Catch ex As System.Exception


        Finally

            If Not IsNothing(oRep) Then
                Response.Flush()
                Response.Close()
                oRep.Close()
                oRep.Dispose()
                GC.Collect()
            End If

        End Try
