FTP program to transfer files server to server?

[dalearyous]

i currently use filezilla and for the most part its great. however, i would like to transfer a file directly between 2 sites. i tried opening both sites in separate tabs but it won't allow me to transfer from 1 site to another.

how do i accomplish this easily and quickly?

Both sites need to support it.
Oh.... I miss the warez slingin' days!

Any FTP server worth running comes with that disabled out of the box these days.

why? is it frowned upon?

It's a security risk. Even more-so than just FTP itself...
