RE: FW: WebFolders on Intranet

Microsoft has no plans for dropping WebDAV in favour of FPSE (FrontPage
Server Extensions) in favour or vice versa. Keep in mind that FPSE
significantly predates WebDAV, and millions of clients and servers (and
not just on Microsoft platforms) are using FPSE. Each of WebDAV and FPSE
have their advantages and disadvantages (for more information on FPSE do
a search from, and, while my comments should not be
taken as a statement of direction, I see a place for both protocols in
Microsoft products for the foreseeable. 

For what it's worth, the Web Folders client is actually a dual-client
supporting both FPSE and WebDAV servers (and automatically detecting
which is supported on a particular URL). Problems with the client should
be pursued through PSS (Product Support), as Gerbert has done. 

To address some of the comments made below by Stewart and others about
WinInet: WinInet is a Windows client API designed to make the job of
sending and receiving HTTP (as well as FTP and Gopher, I think) requests
and responses easier for client applications -- one of which is Internet
Explorer. Note that I'm stressing the word "client." There are a lot of
assumptions that one makes when designing a client API (like there's
only one user, or that it can pop-up UI on the applications behalf --
asking for authentication credentials, for instance). These assumptions
-- which make the client application writer's life a lot easier -- make
it unsuitable for use on middle-tier or servers. XMLHTTP is a another
API (technically a COM object), layered on top of WinInet, that makes it
easy to send HTTP requests that contain XML bodies, and to receive and
parse the XML responses. XMLHTTP this inherits the advantages and
disadvantages of WinInet. WinHTTP and ServerXMLHTTP are new
more-or-less-interface-compatible libraries that are designed for
server-side use. MSDN again has lots of information on these APIs. All
of that proxy stuff below is because WinHTTP and ServerXMLHTTP do not
share proxy configuration information with WinInet (which is configured
via the Internet Options Control Panel -- also accessible through IE's
Tool menu). Since it's intended to be deployed on servers, the
server-side libraries have a command-line configuration interface
instead. In other words, it's all by design :), and for that matter,
since all these interfaces support generic HTTP, they're mostly
irrelevant to Microsoft's WebDAV support.

It is not too surprising that the current versions have intractable
problems; releasing first-version code that works but not quite in all
is pretty standard -- and not only for Microsoft.  Honestly, I give them
lot of credit for implementing the standard at all; I know of no other
company their size who has put WebDAV in both their flagship server
and flagship client (Office2K) products.

However, the response "Why don't you use FrontPage extensions?" does
me.  Is this just ignorance of WebDAV from the support staff (which
surprise me), or does it show a larger disregard for the protocol from
within Microsoft?  FrontPage extensions and WebDAV are -- in many
-- duplicate work.  If MS is dropping WebDAV in favor of FrontPage
extensions, or some other standard even, it could spell doom for a
that has been (to say the least) widely ignored by the technical

Does anyone -- particularly from inside Microsoft -- care to comment on
this?  I'd really like some assurances, especially if they are backed up
with facts, that Microsoft is intending to fix these problems and to
continue to support the WebDAV protocol.

I am not completely sure, if I have understood your mail properly. As
far as
I understand the WebDAV standard, it does not specifiy if the client
connection is done via a proxy or not. For me that means that a client
to support any type of HTTP connection (also if MS is writing the
and if it can not handle direct HTTP it's simply a bug. Any TCPIP client
closes a connection, if the operation should be cancelled or at least
something saying: "Uh, I can't go on". MS WebDAV client does simply

Using a proxy is not really an option in many cases (I am still not sure
it would help with our problem), because NTLM authentication does not
via proxies. Again the WebDAV standard does not mention which HTTP
authentication method has to be used (which is not a flaw at all -
shouldn't have to bother with authentication). Earlier versions of MSs
WebDAV client had severe problems with basic authentication, thus it
well only in combination with NTLM (or perhaps Digest) authentication.

What are you all thinking about this? Our customers pay a whole lot to
Microsoft to use their OSes and Office packages. (We are talking about
companies like Siemens, UBS etc.) Thus MS should provide a WebDAV
implementation, which is usable (at least with their own IIS WebDAV
implementation). First answer we got from all MS support levels was:
don't you use Frontpage extensions?" which renders the IETF standard
