make header like other modules
WebDAV¶
Module: mod_webdav
- Table of contents
- WebDAV
Description¶
The WebDAV module is a very minimalistic implementation of RFC 2518. Minimalistic means that not all operations are implemented yet.
So far we have:
- PROPFIND
- OPTIONS
- MKCOL
- DELETE
- PUT
- LOCK (experimental)
and the usual GET, POST, HEAD from HTTP/1.1.
If you want to setup a WebDAV repository with authentication, make sure you are loading mod_webdav `before` mod_auth.
So far, mounting an open-access WebDAV resource into Windows XP (Network Places), Mac OS X (Finder) and Linux (Konqueror) works. Mounting an authenticated WebDAV resource works in Mac OS X and Linux. The basic litmus tests are passed.
Installation¶
mod_webdav is part of the 1.4.x distribution.
PUT, DELETE¶
If you are only looking for PUT and DELETE support, the basic mod_webdav works for you. No special compile-time options or libraries are required. PUT and DELETE are already part of the HTTP/1.1 spec, but are mostly used in combination with WebDAV.
PROPFIND, PROPPATCH¶
PROPFIND and PROPPATCH are used to do a directory-listing and to attach properties to a file-object.
As this involves parsing of XML-data we need libxml2. To make PROPPATCH work you need sqlite3 to store the properties in a separate location:
- libxml2
FC4:
libxml2 libxml2-devel
- sqlite3
FC4:
sqlite sqlite-devel
To compile mod_webdav with property-support you have to specify: ::
$ configure --with-webdav-props
LOCK, UNLOCK¶
LOCK and UNLOCK are necessary to get mounting of file-systems working. This involves generate unique lock-tokens. We use libuuid for this job.
- libuuid
FC4:
e2fsprogs e2fsprogs-devel
LOCK with includes parsing XML again, so have to provide the dependencies of the previous section and libuuid: ::
$ ./configure --with-webdav-props --with-webdav-locks
Options¶
webdav.activate
If you load the webdav module, the WebDAV functionality has to be enabled for the directories you want to provide to the user.
Default: disable
webdav.is-readonly
Only allow reading methods (GET, PROPFIND, OPTIONS) on WebDAV resources.
Default: writable
webdav.sqlite-db-name
The full path to the file you would like to use as your db file. This is required for webdav props and locks.
Default: <empty>
Examples¶
To enable WebDAV for the /dav directory, you wrap your webdav options in a conditional. You have to use the regex like below as you want to match the directory /dav and everything below it, but not e.g. /davos. ::
$HTTP["url"] =~ "^/dav($|/)" { webdav.activate = "enable" webdav.is-readonly = "enable" webdav.sqlite-db-name = "/var/run/lighttpd/lighttpd.webdav_lock.db" }
If you would like LOCK support ::
$HTTP["url"] =~ "^/dav($|/)" { webdav.activate = "enable" webdav.is-readonly = "disable" webdav.sqlite-db-name = "/var/run/lighttpd/lighttpd.webdav_lock.db" }
note : The WebDAV directory should be a child of the document root. So if you want to add a server.document-root option to the /dav configuration, the path should be a child of the server.document-root (Otherwise move and copy function will not work correctly). (Take a look in mod_webdav.c line 1830)
litmus tests¶
We use http://webdav.org/neon/litmus/ (version 0.10.5) to verify that we support at least the basic of the WebDAV spec.
For now we are far away from 100%.
- we don't handle If: ... headers
- we handle shared locks as exclusive locks
- the failing basic.8 is new in 1.4.13 as we stripped off the fragments for clean URLs
Handle the If: header requires a parser as it contains logical expressions. To give you an overview what works and what isn't: ::
