Symptom
When using WebDAV, you can connect and browse content, but you cannot create new files or folders.
Solution
This occurs when the WebDAV server is using some versions of the Apache 2 Web server. Users of Mac OS 10.0 to 10.1.5 must update to Mac OS X 10.2 or later. Additionally, a configuration change may be required for the server. Refer your server administrator or Internet service provider to this document.
The following directive can be added to the httpd.conf file on the Apache 2 server to fix this issue:
BrowserMatch "^WebDAVFS/1.[012]" redirect-carefully
The httpd.conf file should already contain several BrowserMatch directives for other WebDAV clients. If there is not a BrowserMatch directive for WebDAVFS, then it should be added.
Note: Apache 2, as installed with Mac OS X Server 10.2, includes this directive, but the default installation of Apache 2 may not.
