1.5 Prerequisites/Preconditions

MODUU extensions require a WebDAV server that implements the protocol described in [RFC2518].

Additionally, servers that implement the MODUU extensions also need to support the protocol described in [MS-DWSS].<1>

This protocol also requires a WebDAV client that has URLs which refer to the WebDAV server.

The prerequisite to MODUU, WebDAV, as described in [RFC2518], extends the standard Hypertext Transfer Protocol (HTTP) mechanisms described in [RFC2616] to provide file access and content management functionality for use across the Internet. WebDAV enables an Internet-based file system. However, some tasks—for example, synchronizing server and client copies of the same file—are not easily managed by WebDAV. Also, some protocol interactions, such as obtaining the properties of recently modified files, are less than optimal for large document libraries.
