How do I enable anonymous PUT?
I have enabled anonymous PROPFIND but PUT requires authentication:
2008-02-16 19:16:11 W3SVC2 SERVER 18.104.22.168 PROPFIND /testfolder - 80 - 22.214.171.124 HTTP/1.1 Microsoft-WebDAV-MiniRedir/6.0.6001 - -
www.example.com 207 0 0 805 172 1
2008-02-16 19:16:11 W3SVC2 SERVER 126.96.36.199 PUT /testfolder/Test.mp4 - 80 - 188.8.131.52 HTTP/1.1 Microsoft-WebDAV-MiniRedir/6.0.6001 - -
www.example.com 401 0 5 5347 191 3
<properties allowAnonymousPropfind="true" />
<add users="?" path="*" access="Read, Write" />

Anonymous PROPFINDs are allowed for file listings, but file uploads require an authenticated user.
More specifically, the PUT, MKCOL, PROPPATCH, COPY, MOVE, and DELETE verbs all require authentication.

Is it possible to use a cookie-based authentication scheme by means of a custom authentication module?

Yes - that would be possible. Essentially as long as the request has some means of entering credentials that will be authenticated before the request gets to the WebDAV module in ExecuteRequestHandler, then the WebDAV module will not be aware that you have
implemented some other form of authentication. (Of course, this logic does not apply to Forms Authentication since that is not actually passing credentials via the HTTP headers, only through the HTTP request entity.) So in theory, if you wrote a custom authentication
module that used cookies and a server-side mapping of cookies to user accounts that executed in BeginRequest then you authenticate a user on behalf of a cookie-based client.
I have to state, however, that anonymous uploads via WebDAV are not generally a good idea and I always recommend forcing users to log in. ;-)

Jet 4 Replication Manager uses an anonymous put to upload files. Any thoughts on how we can force this to login?
If not, Internet synchronization of a Microsoft Access database can't happen on IIS 7

There are two considerations for Internet Synchronization that apply here:
