implicit ftp - SSL problem

P: n/a
hi,

i've found out here:
http://forums.microsoft.com/MSDN/Sho...31195&SiteID=1
that FtpWebRequest does not support implicit connections. I have a
serious problem with that, because i need to talk to an Ftp server that
supports only the explicit connections. changing the server is out of
question. and i need ssl to keep login and password secure. to make
things worse i can only log in using ssl. then i need to use Clear Data
channel.

does anyone have any ideas what to do? i didn't dig too deep into this
but is it possible to implement the explicit ssl without rewriting the
whole FtpWebRequest class?

If you really want to do this, your best bet is to write it as an FTP
proxy - but then, why not just buy an implicit SSL FTP proxy, which is far
cheaper than writing it, and use that?

While I'm here, I might as well note that implicit SSL FTP has been
deprecated for well over a year, and was deprecated well before the FTP over
SSL / TLS specification became an official RFC document. Supporting
implicit SSL FTP is a bad idea. It was a dead end before it got started.

use it instead of FtpWebRequest introduced in 2.0 framework.
