IIS host header (bindings) question

Hi, i have a question regarding the host headers or bindings in IIS.

I have a website,

mydomain.com and have added the bindings

mydomain.com 80
www.mydomain.com 80
mydomain.com 443

my question is, i host the DNS records for the domain too,

If i add the dns record forums.mydomain.com is there a way i can bind this to a EXISTING site or directory within a site. Instead of having to create a whole new site.

so if i have the website MYDOMAIN in IIS, and a subdirectory forums with the contents for the forum, how can i add the binding

forums.mydomain.com 80

Thanks guys!!

Under IIS you can set the host header value to the necessary assignment and have it bind to port 80. For example, the value you would use is forums.mysite.com with a binding on port 80. Then in the "basic settings" section you would just want to make sure it points to the proper physical path (i.e., c:\inetpub\wwwroot\mysite\forum). This is assuming you've created a new "site" in IIS and want to go that route.

If it's the same physical site on your server, you could just add an A record to your public DNS info point forums.mysite.com to the proper IP address (extneral). This will route them to your main site; which I assume would have a "forum" hyperlink on it somewhere.

Hope this answers your question.
