Intercept WebDAV requests

[Abhijit]

Hi

I want to use WebDAV for file editing, transfer, etc. At the same
time, I need to store certain information about the file and the user
in a database each time a file is modified/created.

I came across a thread which suggested using IHttpModule. Can I create
a HttpModule interface for a WebDAV virtual directory. It seems like I
need to put the WebDAV directory in a web application or Website,
which has an IHttpModule interface to intercept WebDAV requests.

I am using IIS as the server and IE 6 as my client. Can someone point
me in the right direction?

Thanks,
A.

WebDav support requires processing URI that doesn't map to file name
and more importantly uri that doesn't have file extension at the end.

Example: http://myserver/SomeFolder

Unfortunately, IIS uses the file extension to identify the Web Service
Extension (ISAPI Application)

I could not configure IIS so far to route the http requests that do not have
a file extension to ASP.Net

As per another reply to similar question in
microsoft.public.dotnet.languages.csharp news group, adding an extension map
..* to aspnet_isapi.dll should help.
Unfortunately, the IIS Application Configuration screen doesn't accpt
such mapping. (Complains 'Wrong extension format').

I tried wildcard application map to aspnet_isapi.dll
(with 'Verify file exists' turned off).
As per documentation, this is supposed to route all requests to the
aspnet_isapi.dll
IIS routes all requests only if there is a file extension.

I can see similar question in may news groups, but with no result.
If no luck in few days, I am hoping to open up a support call with MSFT.

One option I am considering is to write a regular ISAPI filter to rewrite
urls with no file extension at end with a dummy extension.

Example: Rewrite http://myserver/SomeFolder as
http://myserver/SomeFolder.noext

Now .noect can be mapped to aspnet_isapi.dll and subsequently routed to http
handlers using web.config.

This way, all WebDav folder info requests can be handled by ASP.Net handlers.

I have not written C++ ISAPI Filter.
Not sure if this is a vialble approach.

If any one has solved such problem, will appreciate feedback.
