Transmit is a commercial WebDAV (as well as sftp and ftp) client for OS/X. It can either browse WebDAV sites in a simple browser, but it's also capable of mounting WebDAV drives using MacFuse.
If you are ok with shelving out a few dollars, this is a much better client than Finder, and is well worth it.
Transmit 4 had issues with multiple namespace declarations (DAV: appeared twice). This bug was promised to be fixed in a next version of Transmit, but it's also fixed in SabreDAV since 1.2.0beta1.
Transmit's client is much better than the built-in OS/X one. It makes far less request, as it seems to buffer all modifications for a while. Because of this it's much more responsive uses far less HTTP requests / bandwidth.
Chunked Request Body problem
Transmit suffers from the same issue as the OS/X client, where it sends all HTTP PUT requests as 'Chunked' transfer encoding. This is not supported by older versions of lighttpd and nginx, or by apache + fastcgi.
If you plan to support Transmit you are strongly advised to just use apache + mod_php.
Note The previous issue may well have been fixed since the last time we looked.
Transmit uses the following user agent:
WebDAVFS/1.2.7 (01278000) Transmit/4.0 neon/0.29.3
Transmit first does an
OPTIONS request on the url, and then a propfind only
Once it's sure it's dealing with a collection, it requests the following properties (depth: 1):
When transmit is used to mount the webdav share, the following useragent is used:
WebDAVFS/1.2.7 (01278000) TransmitFSHelper/1.0 neon/0.29.3
It requests for the same properties as before, as well as the following:
The last 2 are non-standard.
Transmit (or OS/X) also seems to create a
.Trashes folder as soon as the
connection is made.
