URL Re-direction

I have a real ip "xx.xx.xx.xx"

I have 3 websites - all are pointing to xx.xx.xx.xx

like. www.a.com is pointing to xx.xx.xx.xx
www.b.com is pointing to xx.xx.xx.xx
www.c.com is pointing to xx.xx.xx.xx

xx.xx.xx.xx is hosting a website on IIS 6.0

so, when the user types www.a.com or www.b.com or www.c.com, they see
the same website which is hosted on xx.xx.xx.xx

now, i want to redirect www.b.com to xx.xx.xx.xx/b/
likeise, www.c.com to xx.xx.xx.xx/c/

the URL re-direction will work according to the host name, if the user
is typing www.b.com, then xx.xx.xx.xx/b/ should be shown

if the user is typing www.c.com, then xx.xx.xx.xx/c/ should be shown.

if the user is typing www.a.com, then xx.xx.xx.xx should be shown.


how shall i do this is IIS 6.0.


thanks in advance.

best regards.
