WCAP Attachment Support in Calendar Server 6.3

Attachment support has been added to WCAP commands with the addition of new parameters and values.

Users of the Universal Web Client (Communications Express) and the Connector for Microsoft Outlook can put attachments in their events and tasks, and can send attachments with invitations.

As part of attachment support, the following changes have been made to WCAP:

• fetchattachment.wcap: a new command has been added to facilitate fetching of attachments. Only the attachment is fetched, not the event or task data itself.

• deleteattach: a new argument for the storeevents command, used to delete existing attachments from an event or task without deleting the event or task itself.

• fetchattach : a new parameter added to all fetch_by_* commands so that attachments can be returned as well as the event and task data itself.

• sendattach : a new parameter for the storeevents command, used to specify whether the actual attachment is sent with the iTIP invitation, or not.

• X-S1CS-CLIENT-ATTACH-ID : an X-Token containing the attachment's unique identifier. This X-Token is emitted only if the client supplied the attachment ID when the attachment was stored. Otherwise, the actual attachment is sent with the event.

• The deprecated attachments argument, found in the storeevents and storetodos commands, can store URL references to attachments stored outside the Calendar Server data store. This way of using attachments remains for backward compatibility in this release but will be removed from the distribution in a future release.
