webDAV is working great for me from RedHat Linux 9. After I used the webDAV control panel to create a new password protected webDAV directory, I could access my new webDAV folder from Nautilus and Mozilla 1.4.
Nautilus as a drag and drop file transfer tool:
Open a Nautilus window
In the Location: edit box, enter the URL for the directory, e.g., http://www.wombatnation.com/davtest
Open another Nautilus window
Navigate in the second Nautilus window to desired directory on your local file system
Drag files from the second window to the first
Mozilla as an online file editor:
Go to the webDAV-enabled directory
In the Mozilla File menu, select Edit Page
You can now edit the page in Composer (click on the Source tab if you want to directly edit the source)
When you are finished editing, click Publish
In the Publish Page dialog, re-enter the filename
Click the Publish button
I'm not sure why it doesn't default to the same filename.
When you publish the page, you can move it to a new directory on your website, or to a different website entirely.
