Does IIS support wildcard host header
? Can I capture and redirect
*.mydomain.com to one web site ? The answer is Yes/No. Yes, because you are
able to redirect *.mydomain.com to one
web site. No, because the magic is in
DNS and not IIS.
Here's how you do it: At IIS MMC,
configure a web site with NO host
header, then assign an IP address to
the site. (if you have one IP address
in the box, then you can skip this).
With this, the web site will bound to
the specific IP and will listen to all
HTTP requests send to the IP, and you
are done :)
Next step is to make sure your name
resolution works for the wildcard
query and reply with the correct IP
address. If you using Microsoft DNS
service, it won't allow you to create
a '*' A record (assuming you already
created the domain zone in DNS MMC),
you need to do the following:
a) Navigate to %windir%\system32\dns\
b) Find the zone file. E.g.
mydomain.com.dns, open it with Notepad
c) Add an entry. E.g.
* A IP.IP.IP.IP d) Save the zone data file e) Reload the zone data
in DNS MMC.
Take note that by doing this, all *
will response to the IP that you
configured earlier. E.g.
abc.mydomain.com, www.mydomain.com,
K2k.mydomain.com and etc.
To verify that it is working, try ping
utility Ping (insert anything
here).mydomain.com .. and you should
get replies from IP.IP.IP.IP
Then try browsing, http://(insert
anything here).<>mydomain.com/, you
should get the same web page that you
have configured.
