Redirecting Host Headers to specific sub dir in same IIS
app?

Ok, I've been asked to accomplish somthing kinda strange by the marketing types
in our organization.  I won't bore you with the why unless somebody asks. 
Here's the 'what' of the situation.

We have a single IIS instance that has three host header names configured to
serve from that IIS instance.  Let's say:

http://www.thedomain.com

http://theFirst.theDomain.com

http://theSecond.theDomain.com

What I've been asked to do is always route requests to the HTTP hosts where a
sub domain is present, to a specific sub directory  within the IIS instance, but
only when the request is for the HTTP Host and no other sub directory in the URL
.  

So it would work like this.

http://theFirst.theDomain.com would be forwarded to
http://theFirst.TheDomain.com/theFirst/ 
AND 
http://theSecond.theDomain.com/ would be forwarded to
http://theSecond.theDomain.com/theSecond/
BUT
http://theFirst.TheDomain.com/somethingElse/ would not be forwarded but rather
allowed to be served normally because it was a specific request for a directory
below the root.

If all requests to the HTTP Host could be forwarded to a specific location, I'd
probably just setup individual IIS instances and autofoward to a second
location, but, in this case I've been asked to only forward to a specific
location if the HTTP Host is a sub domain, and, the URL contains nothing but the
HTTP Host.

Make sense?

Anyone got any ideas?

Thanks!

I think the easiest was to do this would be to use a client side redirect in the
HTML header tag or a server side Response.Redirect on the default page for the
site.

Yep, it sure would.  I was really trying to over think this one by intercepting
the HTTP request and writing some kind of ISAPI or....  Sometimes the simplest
solution is the best.

Thanks!

Exactly!  Are you clear on what to do?

Yea, I can take it from here.  

You beat me to responding to my own post. 

Thanks again for the response.
