Websocket messages not all readable

[Emeric]

Hi,

Thanks for Fiddler and Fiddlercore. I use Fiddler to inspect websocket messages but not all messages are readable.

some message are readable but some are in this format :    j 0p { <  D  A  ZO vұ ....

What's happening as I'm not a real developer ...

Thanks

Hi,

I've tested CharlesProxy to see if websocket messages are readable and they are ! So I think there's something wrong in Fiddler websocket part.

Perhaps is there a problem in PayloadAsString method ?

Please note that results are the same in Fiddlercore that is my first need, I donwloaded Fiddler app to Check Fiddlercore reliability.

Thanks.

    Public Sub OnWebSocketMessageHandler(Sender As Object, e As WebSocketMessageEventArgs)

            Dim FirstByte As New BitArray(New Byte() {e.oWSM.ToByteArray(0)}) 'Get first byte from header
            Dim UseDeflate As Boolean = FirstByte.Get(FirstByte.Length - 2) 'Get 2nd bit value (RSV1)

            Dim Response As String = Nothing

            If UseDeflate Then
