# Apache Module mod_dav

Description: | Distributed Authoring and Versioning (WebDAV) functionality
Status: | Extension
Module Identifier: | dav_module
Source File: | mod_dav.c

### 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>
