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

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

The WebDAVS component is the SSL-enabled equivalent of the IP*Works! WebDAV component. The main difference is the introduction of a set of new configuration settings, properties and events that deal with SSL security. The SSLProvider configuration setting chooses a security provider subsystem. The SSLEnabledProtocols and SSLCipherStrength configuration settings determine which protocols are enabled and at what security level. The SSLCert property is used to select a client certificate if the server is requesting client authentication. The SSLSecurityFlags configuration setting, together with the SSLServerAuthentication event allow you to check the server identity and other security attributes. Finally, the SSLStatus event provides information about the SSL handshake.

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

The ListDirectory and FindProperties methods will list the properties of a resource properties 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.

A number of operations can be performed on resources by using the various methods of the component. 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 properties , which is filled automatically when retrieving DAV responses, but must be filled manually when requesting non-standard properties.
