Re: Redirection of HTTP request
GG> Summary: domain.com A --> mail server IP

GG> www A --> NT server IP
This is what I would do with reasons:
domain.com A --> web server IP
because people will type domain.com. Netscape will try www.domain.com
if nothing is listening at www.domain.com, IE won't AFAIK. What seems
more elegant, domain.com CNAME --> name of the virtual hosting server,
will not work because you cannot CNAME domain.com if you define other
RRs under domain.com.
www.domain.com CNAME --> domain.com
so www works!
domain.com SOA --> dns1.primedomain.com,admin.primedomain.com
domain.com NS --> dns1.primedomain.com
OK. You need another NS preferably on a different T. This is not
some paperwork requirement, you want the domain name to resolve even
if there is an outage.
domain.com 10 MX --> mail server name
domain.com 20 MX --> back-up mail server name
Always try to accept mail even if the main server goes down (you don't
know when the other daemons in the net will bounce queued mail, but
you can adjust this on your back-up if there's an outage).
On terminology: 'redirection' is not a good term to use in this case.
In the context of http, it has a different meaning that does not
concern DNS. EG: An http redirect tells a browser that hit
www.domain1.com to go to www.domain2.com _at the HTTP level_. This
is useful because it enables you to redirect, say, http://company.net/ to
http://www.company.com/ and cause the location shown in the browser
and remembered in bookmarks to change to http://www.company.com/.
hope this helps,
