Detailed Description

Class ilClientNodeDAV.

This class represents the used ilias client. For example if your clients name is "my_ilias" and you are currently in the directory with the ref_id=123, the path would look like this: ilias.mysite.com/webdav.php/my_ilias/ref_123/

The call would look like this: -> webdav.php <- creates the request handler and initialize ilias -> ilWebDAVRequestHandler <- setup the webdav server -> ilObjMountPointDAV <- This represents the "root" node and is needed for sabreDAV -> ilMountPointDAV <- This class represents the used client (for example here it is my_ilias) -> child of ilContainerDAV
