Module mod_dav

This module provides Distributed Authoring and Versioning (WebDAV) functionality.

Status: Extension
Source File: mod_dav.c
Module Identifier: dav_module

Summary

This module provides class 1 and class 2 WebDAV ('Web-based Distributed Authoring and Versioning') functionality for Apache. This extension to the HTTP protocol allows creating, moving, copying, and deleting resources and collections on a remote web server.

To enable mod_dav, add the following to a container in your httpd.conf file:

Dav On

Also, specify a valid filename for the DAV lock database by adding the following to the global section in your httpd.conf file:

DavLockDB /tmp/DavLock (Any web-server writeable filename, without an extension)

Dav

Syntax: Dav on|off
Default: Dav off
Context: directory
Status: extension
Module: mod_dav
Compatibility: Apache 1.3.4 and above

Use the Dav directive to enable the WebDAV HTTP methods for the given container. You may wish to add a <Limit> clause inside the location directive to limit access to DAV-enabled locations.

Example:

DavLockDB /tmp/DavLock



<Location /foo>

Dav On



AuthType     Basic

AuthName     DAV

AuthUserFile user.passwd



  <LimitExcept GET HEAD OPTIONS>

  require user admin

  </LimitExcept>

</Location>

DavLockDB

Syntax: DavLockDB filename
Default: None
Context: server config, virtual host
Status: extension
Module: mod_dav

Use the DavLockDB directive to specify the full path to the lock database, excluding an extension. The default (file system) implementation of mod_dav uses a SDBM database to track user locks. The utility modules/dav/util/lockview can be used from the server to display all locks in a lock database.

Example:

DavLockDB /tmp/DavLock

DavMinTimeout

Syntax: DavMinTimeout seconds
Default: DavMinTimeout 0
Context: directory
Status: extension
Module: mod_dav

When a client requests a DAV resource lock, it can also specify a time when the lock will be automatically removed by the server. This value is only a request, and the server can ignore it or inform the client of an arbitrary value.

Use the DavMinTimeout directive to specify, in seconds, the minimum lock timeout to return to a client. Microsoft Web Folders defaults to a timeout of 120 seconds; the DavMinTimeout can override this to a higher value (like 600 seconds) to reduce the chance of the client losing the lock due to network latency.

Example:

<Location /MSWord>

DavMinTimeout 600

</Location>

DavDepthInfinity

Syntax: DavDepthInfinity on|off
Default: DavDepthInfinity off
Context: directory
Status: extension
Module: mod_dav

Use the DavDepthInfinity directive to allow the processing of PROPFIND requests containing the header 'Depth: Infinity'. Because this type of request could constitute a denial-of-service attack, by default it is not allowed.
