WebDav VS FTP

来自WebDav官方FSQ:http://www.webdav.org/other/faq.html

Q.Why should I use DAV instead of FTP?
A.Since DAV works over HTTP, you get all the benefits of HTTP that FTP cannot provide. For example: strong authentication, encryption, proxy support, and caching. It is true that you can get some of this through SSH, but the HTTP infrastructure is much more widely deployed than SSH. Further, SSH does not have the wide complement of tools, development libraries, and applications that HTTP does.

DAV transfers (well, HTTP transfers) are also more efficient than FTP. You can pipeline multiple transfers through a single TCP connection, whereas FTP requires a new connection for each file transferred (plus the control connection).
