Winsock: HTTP File Upload

[visualAd]

You need to authenticate yourself using NTLM (Microsoft Windows NT LAN Manager) authentication. It is possible to do this in VB but involves a lot of byte shifting and code.

NTLM is a challenge response protocol. That means the client needs to make a connection containing a challenge and the server makes the response. No user name and password are ever transmitted to the server - the authentication takes place with the domain controller.

Like I say. I have never written an NTLM authenticator in VB and I do not plan to either. That doesn't mean the its not possible, just that its a complex and time consuming task.

If you want to do it yourself here is a detailed specification.

Hi, If you want add support for http authentication you could add that line in the source:

    ' construct the HTTP request in the form:
    '
    ' POST /path/to/reosurce HTTP/1.0
    ' Host: host
    ' Content-Type: multipart-form-data, boundary=boundary
    ' Content-Length: len(strbody)
    '
    ' HTTP request body
    strHttp = "POST " & DestUrl.URI & "?" & DestUrl.Query & " HTTP/1.0" & vbCrLf
    strHttp = strHttp & "Host: " & DestUrl.Host & vbCrLf
    ' HTTP Authentication LINE BELOW HERE
    strHttp = strHttp & "Authorization: Basic YWRtaW4xNDptdXNpd2ViMDMwNg==" & vbCrLf
    strHttp = strHttp & "Content-Type: multipart/form-data, boundary=" & strBoundary & vbCrLf
    strHttp = strHttp & "Content-Length: " & lngLength & vbCrLf & vbCrLf
    strHttp = strHttp & strBody

    BuildFileUploadRequest = strHttp
