How can I redirect request to my virtual folder? thank you very much!

Hi,

I am implementing a webdav, so I need map all requests to my httphandler,
for example, I created a vritual folder davfiles, every calls llike
http://localhost/deavfiles/helpme.doc will go to my httphandler. That works
fine. But I have no way to capture request to http://localhost/deavfiles/ or
http://localhost/deavfiles, someone suggested me to add default document to
handle it. But it didn't work, since the requests are not normal webpage
request. I guess what I need to know is how IIS handle request to a virtual
folder, how can I redirect the call to my httphandler? I suspect httphandler
may not be able to handle it, so do I need use ISAPI? if so, any suggestion?

Thanks!
