integrating secure ftp

I am working on an existing system that uses a flash interface with coldfusion. I want to allow a user to choose a file to upload to our server using secure ftp rather than http because we are moving large files and the htttp protocol often times out. Furthermore, it must work across all platforms, including mac. Currently, we are using a java applet that doesnt cut it.

Is there a way to do this using flash or cfml rather than using an ftp client.

have you tried using cffile and cfftp?

cfftp is used only for server to server, in other words the coldfusion server can connect to other ftp servers to upload, but it cannot act as a client. However, I am not sure how cffile works. I know that it can upload files, but I think that it uses http rather than ftp.

any other suggestions?

Thanks

can you have them browse for the file using input type file through a form and then use cfftp

I would like for any end user to be able to ftp a file directly because of the problems I described earlier. Would this method effectively act like an ftp client? Is it secure?

The client can upload a file just as they always have, using a form field with the file field type. You can do this over SSL and it would be encrypted.

Is there a way to select multiple files all at once and then upload them all at once?

Not with a standard form control, this is a limitation of the browser. But there are ActiveX controls and Java applets that will do this.
