WebDAV Bean

Properties Methods Events Configuration Settings Errors

The WebDAV Component implements an easy-to-use interface to the Web Distributed Authoring and Versioning protocol (WebDAV).

Syntax

IPWorks.Webdav

Remarks

The bean allows remote management of resource properties and collection , including creation, deletion, listing, copying, and moving. Resource locking is also supported.

The ListDirectory and FindProperties methods will list the properties of a resource collection or resource, and a DirList or ResourceProperties event will be fired for each matching resource.

Depth is used to determine which resources or properties are retrieved from the server. A depth of ResourceOnly will return only the resource associated with ResourceURI, or its properties. A depth of Infinity will return all resources contained within hierarchy, or their collective properties.

Note: Some servers (such as IIS 7.5) may not support a depth of Infinity by default and may return a HTTP 403 Forbidden response.

A number of operations can be performed on resources by using the various methods of the bean. Please refer to the individual methods for more information.

WebDAV allows non-standard properties to be specified through XML namespaces.

The namespaces are provided in the Namespaces collection , which is filled automatically when retrieving DAV responses, but must be filled manually when requesting non-standard properties.
