[Nfb-web] Pointing to Multiple Hosts

[Peter Donahue]

Hello John and listers,

    What this amounts too is a lack of knowledge of how to build a site on
another server while keeping the existing site viewable by the public. This
is another example of Marine Captain Pete Donahue going in first and
conquering new ground for our cyber presence. Your explanations go a long
way to helping me understand how to do this. I once said that you'd be a
great I.T. professor. Thanks for the assistance.

Hi, Pete.  I'm not certain what you're trying to accomplish by pointing
the domain to multiple hosts.  There are techniques for failover--should
the primary host fail, a secondary host will kick in so the site remains
available.  I don't get the impression, however, that this is your
intention.  To build a site while the original is still up and running,
you could use a temporary domain as a place holder and access it through
this temp domain name.  When everything is ready to go, you move the
files to the correct domain.  If you can bind an IP to the domain name,
you can use the actual domain and access the new site via IP address
until it's ready to go live.

Regarding your questions:

1. As far as I know, a domain can exist in only one place (aside from
the failover situation)
2. Keep the DNS records as they are now and people will continue to see
the site they've always visited.
3. When your new site is ready for prime time, you change your DNS
records to point to the new host.  The shift will typically take 12-36
hours to propagate.
4. Colocation typically refers to a data center that leases server space
(physical or virtual) to multiple companies.

Regards,
John

Hello everyone,

    I have a Web site we're making over during the next few months. One
of the individuals receiving this email developed her own content
management system that runs under ColdFusion. Unless I'm informed
otherwise our current
host doesn't support any flavor of ColdFusion.     The organization all
ready has a registered domain. Our question is is it possible to point
the domain to multiple hosts so we'll have all of the functionality
available on the new host when a domain is pointed to it, but keep the
current Web site as the default site visitors see when they visit the
organization online while the new site is being built? When the new site
is ready to go live we would redirect visitors to it. My original
question breaks down in to
several:

1. Can we point the current site domain to multiple hosts?
2. How do we keep the current Web site as the default site people see
when they visit us online?
3. Once the new site is ready to go public how do we redirect visitors
to it?
4. Isn't this what is commonly referred to in the Internet World as a
colocation?

    Thanks for educating all of us on what to do,a nd ow best to do it.

Peter Donahue
