Is it possible to use C# FTPWebRequest through a FTP proxy?

Question

As I understand it, the FTPWebRequest.Proxy property denotes an HTTP proxy. I have to issue FTP requests to an external server via an FTP proxy.

The only way I've got this to work so far is by creating a script which uses the Windows FTP command and downloading that way.

Is it possible to use the FTPWebRequest to download files via an FTP proxy?

Answer 1

If you have the budget for it - Dart do some great classes for this:

Answer 2

They claim it is possible to list, listdetails, and download through a proxy. However I could not get this to work with an isa firewall. So I disabled the default proxy in my app.config and added an application rule for ForeFront/ISA client. To do this I created a file c:\programdata\microsoft\firewall client 2004\application.ini with the contents:

[applicationName] DisableEx=0 Disable=0 NameResolution=R

where applicationName is the running exe minus the .exe extension.
