RE: HTTP listening ports and URL questions

DNS doesn't pertain to port numbers, only IP address.

I have asked this question before and do not remember an answer that
dealt with the question.

Why not use the DNS on your iSeries? So, for example, an iSeries named
Thor might have a section named ThorAR and resolve to 1.0.0.1:461 and
another section named ThorAP could resolve to 1.0.0.1:6060. Then comes
the fun of creating a logical naming scheme, but that gets to be fun.

Then your users and programmers do not need to concern themselves with
port numbers, etc. That becomes an exercise for whomever handles the
DNS.

Since no one suggested this solution there must be a reason not to do
it. And yes, I understand I will undoubtedly be mortified when I read
the answer. But in this case my curiosity outweighs my fear of
humiliation.

I have some questions related to HTTP listening ports and URLs.
I have a current instance listening on port 443, all IPS.

I have a new app going live that we prefer to listen on port 443. It

can listen on a different port, but I've been told that if 443 is not
used, then we must include the port number in the URL.

We would like to have the new app keep the same URL as the old current

app, which is listening on port 80.

So my issue is that I will have two http apps listening on port 443.
Options.
1) Create one http instance for both, using virtual host. The problem

with this option is that when one app needs to be shutdown, we don't
wish to shut down the other app.

2) Have both apps listen on 443, two http instances, different IPs.

I'm leaning towards this solution.

3) Are there others?



Thank You
