CalDAV uses WebDAV as its underlying transport mechanism. WebDAV, which stands for Web Distributed Authoring and Versioning, extends the capabilities of HTTP, allowing users to manage files on remote web servers. It provides essential functionalities for collaborative editing and management of documents.

CalDAV, specifically, builds on WebDAV to facilitate the management of calendar data. It allows clients to access and manage calendar events and scheduling information on a server using HTTP requests. This integration enables interoperability among different calendar applications and services, making it a widely adopted protocol for sharing and synchronizing calendar information over the web.

While HTTP is the protocol used for communication, it's vital to note that CalDAV operates on top of WebDAV specifically for calendar data management. Other transport mechanisms like FTP and SMB are not relevant to CalDAV's functionality as they serve different purposes, primarily focusing on file transfer and network file sharing, respectively.
