IIS Host Headers With * in DNS

Hi,

I'd like to setup the following. I have a website (lets call it
isnice.com) and I want to add a subdomain for each user that
registers.

To avoid lots and lots of manual labour I set it up in the DNS as
following:

* IN A 10.0.0.1

Ie, all requests that has anything to do with isnice.com will end up
at my IP.

Now, to IIS, I don't want to have to set up each subdomain as Host
Header in IIS. What I would like to do is assign *.isnice.com to a
hostheader and then determine programatically which domain is called
with the server variable HTTPHOST.

But IIS is refusing me to use any wildcards in Host Headers. Does
anyone have a solution to this?

Don't use host headers. What you're trying to do is effectively have
any request to the IP address defined in your DNS processed by a
single web site page that will branch based on the header. That's
what IIS does normally if you don't use any host headers.

That would normally work fine. The only problem is that there are
already sites on that IP address that I'm not allowed to tamper with.
