[APACHE DOCUMENTATION]

Apache HTTP Server Version 2.0

Apache Module mod_dav

Description:Distributed Authoring and Versioning (WebDAV) functionality
Status:Extension
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 writable filename, without an extension)

Directives

Dav Directive

Description: Enable WebDAV HTTP methods
Syntax:Dav on|off
Default:Dav off
Context:directory
Status:Extension
Module:mod_dav

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>

DavDepthInfinity Directive

Description: Allow PROPFIND, Depth: Infinity requests
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.

DavLockDB Directive

Description: Location of the DAV lock database
Syntax:DavLockDB file-path
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 Directive

Description: Minimum amount of time the server holds a lock on a DAV resource
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>
