[VB.NET] Timeout WebException when connecting repeatedly to web server

[gpstefansson]

Hi all,

I have a web server that I retrieve information via a Xml file from and when I call it frequently, I eventually receive a timeout exception (System.Net.WebException).

Public Function ReadTags() As String(,)
        Dim retArray(2, 10) As String 
        Try
            Dim m_xmlr As New XmlTextReader("http://192.168.2.40/cgi-bin/dataProxy?oper=queryTags")
 
            m_xmlr.Read()
 
            ' ... rest of function... 
 
            Return retArray
            m_xmlr.Close()
            retArray = Nothing
        Catch ex As Net.WebException
            ' Do something here 
        End Try
    End Function

Under some circumstances, the function above can be called repeatedly, and when that happens, I want the function to handle that situation in some way so that the timeout does not occur. When the function is called repeatedly the information returned is not of any relevance so the function can just stop responding really, and just give no data back.

Maybe I should shorten the timeout to a few seconds and just grab the error an do something there, but I do not have time to wait the standard 100 seconds, that it takes the timeout exception to be generated.

I am not sure what is the standard way of dealing with this sort of problem on the Client side, so if you have any suggestions on how to handle this situation, please submit them here.

Best regards,
G
