- WebDAV provides authoring and file access features via HTTP (it is
- in fact an extension to it). This fits very well with Wiki, and a
- nice client assumed provides another useful page editing interface.
-
- This snippet is innovocated by "z.php", and itself depends upon a
- modified version of the HTTP_WebDAV_Server module (originally PEAR).
- It does not yet work together with _PROTECTED_MODE settings, that's
- why "fragments/funcs/auth.php" should be used meanwhile (as always),
- even if the WebDAV standard actually forbidds to use the Basic auth
- mechanism (most implementations ignore this stupid rule, and as it
- is AntiWiki we ignore it even harder).
-
- Because ewiki has a really flat namespace (despite of subpages, we
- don't have PageGroups or SubWikis fired up per default), and even
- pagenames with a slash inside won't be treated as directories in
- any case. That's why the implementation of our WebDAV interface is
- much shorter than for other systems.
-
- - not tested at all
- - likely to work with Wiki pages only (handling of _BINARY entries
- is undefined)
- - enriched with content-coding (compression) support, though it'll
- only work for GET and PUT (won't patch the WebDAV class), but
- todays WebDAV clients are plain stupid in this regard anyhow
- - use the "plugins/debug/xerror.php" script together with this, if
- you'd like to see error messages (for debugging)
