Limits

A single WebDAV request can carry a large file, or ask for thousands of resources in one response. The limits of the DAV services protect the server from requests that would use excessive memory. They are set on the WebDav singleton (found in the WebUI under Settings › Network › WebDAV), and they take effect after a settings reload.

maxRequestSize is the largest request body accepted, 25 MiB unless changed. It applies alike to uploaded files, to imported calendar and address book entries and to XML requests. Accounts with the unlimitedUploads permission are exempt.

maxResults is the largest number of resources returned in one PROPFIND or REPORT response. The limit does not hide anything from clients, which receive the rest in further requests.

maxLivePropertySize is the largest value that a client can set for a property the server interprets, such as a collection’s display name.

Two other kinds of data are limited elsewhere. The size of dead properties, which the server stores without interpreting them, is limited by the object metadata settings. The size of the calendar events and contacts themselves is limited by the calendar and address book settings, described in Calendars and Contacts.
