Hi to all,

I have made up a small client / server application with WinSock (port 443)
at VB6.

I have install server in my Home, and client is running behind a proxy
server.
Client cannot reach server, because proxy requires NTLM Authorization before
redirecting.

Is there any tested code , able to NTLM authenticate such a proxy server?

Regards

You need to use the Winsock API to get the job done

Here is a good place to start looking for examples

Dear Max,

Thanks for your time, but NTLM is a bloody thing.
I really can't understand what you mean Winsock API,
bythe way, if you have a look at guidelines of NTLM Authorization , it seems
almost impossible to generate the correct responses to proxy server and gain
acess.
I was hoping somebody to have some usefull code for further studing..

Regards

George

Hi George

You are correct NTLM is a pain and it would be a "challenge" to write you
own code to autanaticate against it.

However like most things in windows there is an Application Programing
Interface (API) to what Microsoft has done, in this case the Winsock API
provides for communication over TCP IP directly or via any other proxy NTLM
included.

For this reason you will not find many code examples to Authanticate against
NTLM but you will find truck loads of VB6 code on how to hand the entire job
of moving the data between the PC's over to windows so you can simply deal
with the results.

The link I provided is the best place to start it has several working
examples of code that will work via NTLM.
..
