WebDAV for Plone
Setting up Zope instance to allow webDAV connections
There's a general how-to on plone.org: http://plone.org/documentation/how-to/webdav
One of the comments includes details on setting this up with buildout. There are not recipes yet, so it uses zope-conf-additional.
Add the following to the [instance] section of buildout:
zope-conf-additional =
enable-ms-author-via on
<webdav-source-server>
address YOURPUBLICIPADDRESS:8484
force-connection-close off
</webdav-source-server>
Rerun buildout (offline mode):
$ bin/buildout -o
Restart the site:
$ bin/instance restart
Testing the configuration:
$ telnet YOURPUBLICIPADDRESS 8484Type in random text to see that the server answers with "invalid request"
