/**
|
|
* CalDAV Handler Module
|
|
*
|
|
* This module implements the CalDAV protocol (RFC 4791) endpoints for OxiCloud.
|
|
* It provides calendar access and management through standard CalDAV methods,
|
|
* allowing clients like Thunderbird, Apple Calendar, and GNOME Calendar to sync.
|
|
*
|
|
* Supported methods:
|
|
* - OPTIONS: Advertise CalDAV capabilities
|
|
* - PROPFIND: List calendars and their properties
|
|
* - REPORT: Query events (calendar-query, calendar-multiget)
|
|
* - MKCALENDAR: Create a new calendar
|
|
* - PUT: Create/update calendar events (.ics)
|
|
* - GET: Retrieve calendar event data
|
|
* - DELETE: Remove calendars or events
|
|
* - PROPPATCH: Modify calendar properties
|
