FTP upload through proxy

[dc79it]

Hi,

I hav'been searching the groups for a way to _upload_ a file
to a ftp site using a proxy server with URLLIB (1 or 2) or FTPLIB.

I can download a file from a ftp site through the proxy - but I need
to be able to upload.

There are some postings about file uploads using http_post but none
mentioned ftp uploads using urllib2 over proxy server ...

Has anyone done this ? Can it be done ?

Thanks
