本文对比了DAV（Distributed Authoring and Versioning）与FTP的功能。DAV通过HTTP进行工作，因此它提供了FTP无法提供的多种优点：强大的认证机制、加密、代理支持以及缓存功能。尽管SSH也能提供部分这些功能，但HTTP基础设施比SSH更为普及，并且拥有更多的工具、开发库和应用支持。此外，DAV传输相较于FTP更高效，可以在单一TCP连接中并行多个文件传输，而FTP则需要为每个文件建立新的连接。

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.
[color=red]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)[/color].
