Overview

FXP is an extension to the FTP protocol which allows for server to server transfers without actually acquiring the files yourself.  For example, imagine that you wish transfer files from server A to server B using the FTP protocol from client C.  Normally when using the FTP protocol you would have to do the following:

As you can see this process is an inefficient use of bandwidth as it requires that a file be transferred twice in order to get to it's final destination.  This can be especially problematic when the client has a slow connection such as a dialup connection.  FXP solves this problem by allowing the client to issue a series of commands which transfers the files directly from server A to server B without first acquiring the files by client C.
