(Excel) Demonstrates KeepSessionLog and SessionLog

The Chilkat Socket component provides properties for keeping a session log making it possible to see the exact bytes received and sent on a TCP/IP or SSL/TLS connection. To enable session logging, set the KeepSessionLog property = True. The SessionLogEncoding property controls how binary, non-printable bytes are represented in the log. There are two possible settings: Possible values are "esc" and "hex". The default value is "esc".

When set to "hex", the bytes are encoded as a hexidecimalized string. The "esc" encoding is a C-string like encoding, and is more compact than hex if most of the data to be logged is text. Printable us-ascii chars are unmodified. Common "C" control chars are represented as "\r", "\n", "\t", etc. Non-printable and byte values greater than 0x80 are escaped using a backslash and hex encoding: \xHH. Certain printable chars are backslashed: SPACE, double-quote, single-quote, etc.

' This example assumes the Chilkat Socket API to have been previously unlocked.
' See Socket Unlock Sample for sample code.

Dim socket As Chilkat.Socket
Set socket = Chilkat.NewSocket

' Enable session logging:
socket.KeepSessionLog = True
socket.SessionLogEncoding = "esc"


tls = True

maxWaitMillisec = 20000

success = socket.Connect("www.chilkatsoft.com",443,tls,maxWaitMillisec)
If (success <> True) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

' Send a GET start line to the web server..
success = socket.SendString("GET /abc123.abc123 HTTP/1.1" & vbCrLf)
If (success <> True) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

' Send some bytes that will cause an error...
Dim binData As Chilkat.BinData
Set binData = Chilkat.NewBinData
Dim success As Boolean
success = binData.AppendEncoded("01020304","hex")
success = socket.SendBd(binData)

' Read the response up to the first double CRLF:

httpHeader = socket.ReceiveUntilMatch(vbCrLf & vbCrLf)
If (socket.LastMethodSuccess <> True) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

' Close the connection with the server
' Wait a max of 20 seconds (20000 millsec)
success = socket.Close(20000)

' Display the session log:
Debug.Print socket.SessionLog

' The Session log will show the exact bytes sent and received.
' In this case, the session log shows:
