AND the code I use is

        Dim wr As WebRequest
        Dim wResp As WebResponse
        Dim sr As StreamReader
        Dim Shtml As String
        If InStr(Request.ServerVariables(&quot;path_info&quot;), &quot;ava-006&quot;) &gt; 0 Then
            wr = HttpWebRequest.Create(&quot;http://&quot; &amp; Request.ServerVariables(&quot;server_name&quot;) &amp; &quot;/ava-006/lead.report.agingsub.aspx?pFormat=&quot; &amp; strFormat &amp; &quot;&amp;pWeek=&quot; &amp; strWeek)
        Else
            wr = HttpWebRequest.Create(&quot;http://&quot; &amp; Request.ServerVariables(&quot;server_name&quot;) &amp; &quot;/lead.report.agingsub.aspx?pFormat=&quot; &amp; strFormat &amp; &quot;&amp;pWeek=&quot; &a开发者_如何学运维mp; strWeek)
        End If
        wResp = wr.GetResponse
        sr = New System.IO.StreamReader(wResp.GetResponseStream)
        Shtml = sr.ReadToEnd
        GetReport = Shtml
    End Function</pre>

error is in your page lead.report.agingsub.aspx when its pass pFormat and pWeek its throw error so its display error 500 because wr.GetResponse return error from page lead.report.agingsub.aspx
