FTP File Upload with HTTP Proxy

Question

Is there a way to upload a file to a FTP server when behind an HTTP proxy ?

It seems that uploading a file is not supported behind an HTTP Proxy using .Net Webclient

Answer 1

most FTP proxies do their thing on the connection, so if you had NO proxy, you do this:

• server: myftpserver.com
• user: me
• password: pwd

using an FTP proxy, you do:

• server: ftpproxy.mydomain.com
• user: me@myftpserver.com
• password: pwd

and it just works it out from there. I'm using this RIGHT THIS SECOND (trying to debug something) thru a squid proxy.

... but as you dont have an FTP proxy....

Do you have a SOCKS proxy? That might work, but I dont know if .NET can do it. Otherwise, to be honest, I think you are stuck! FTP is an "odd" protocol, when compared to HTTP, as it has a control channel (port 21) and a data channel (or more than one, on a random port), so going via proxies is.... fun to say the least!
