Hello,
using latest library version, I'm trying to implement a SSL Client to talk synchronously with a server. I can connect, verify server certificate, send data and read responses from the remote server, but my problem is the response I read appears to be always the same (the first)!
E.g.:
- send MSG 1
- get RESPONSE1
- send MSG 2
- get RESPONSE1 AGAIN!
it looks like I always read the same response from server, while I'm assured I should get another kind of response for my MSG 2 (which btw is different from MSG 1).
I cannot understand what happens: should I move forward some pointer (position?) on my SecureSocket?
I get the same behaviour both using SecureSocket or SecureTcpClient, so I believe I miss something.
Does anybody use this great library for synchronous communications? Can anybody help?

After futher testing, I could partially solve the problem: I need to read all data available on the socket, for example:
While nsStream.DataAvailable = True
sb = nsStream.ReadByte()
If sb = -1 Then Exit While
sb2.Append(ChrW(sb))
Debug.WriteLine("AVAIL: " & nsStream.DataAvailable)
End While
The strange problem is I have to put a delay in the loop: if I comment out the Debug line, I always get partial messages from the server! That is my code exits the loop before it has read all data.
Is there a timeout or something to play with to change this behaviour? I mean, what causes DataAvailable to become False?
