Ok Thank you, I will try that and come back to you ?
I'm connecting to a distant SFTP server using the winscp dll and it work perfectly when there is nothing protecting the network.
Now I would like to know how I can connect but passing by a proxy ?
Is it possible ?
If I connect to the sftp serveur using a browser it works because the browser already handles the proxy but how can I do it without using the browser ? Or how can I use the browser to connect using the dll ? And the browser must be not visible to the user.
Thanks for your help.
