Thanks for your response Mike,
WebDav is a public standard file/data transfering protocol over HTTP,
Microsoft's exchange server first implement it and IIS server also provide
support on it:

Also, as for the following things you mentioned,
====================
PS. Someone mentioned coding my own HttpModule. Would that make a marked
improvement, you think?
===================
I think HttpModule will be a bit better because httpmodule process the
request at the begining of ASP.NET serverside pipeline so that it'll cause
less overhead than an asp.net httphandler or page handler....
In addition, generally speaking, for uploading file over HTTP protocol to
IIS webserver, using the raw ISAPI filter will be the best choice from
performance perspective...... Here are some related articles discussing
on creating file upload ISAPI component:

Hope also helps. Thanks,

| Thanks, Steven.

| Can you point me to some "getting started" guide for using WebDav,
please?
| I'm new to it.
|
| Although I mentioned the intranet, we intend using the site over the
| Internet, but since upload speeds are so awful, we're restricting it to
| intranet for now.
