Re: HTTP listening ports and URL questions

I'd be dead without a reverse proxy. I have a dozen or so internal addresses bound to the TCP interface and then one external IP. I map that external address to one internal address and then that internal address is my one reverse proxy instance on Apache. Then the dozen or so other Apache instances can be started and stopped and the "proxy" instance is just used to direct traffic back to all the server instances, some of which aren't even running on IBM i (Linux running Nagios is one example....)

It's so simple that I can add and drop hosts and domains on a regular basis as I experiment.

Wowza. That's a lot.

I have a number of web servers (Node.js/Ruby) running on spaces.litmis.com
and instead of going the route of doing new IPs I do the reverse proxy
approach. I am trying to imagine advantages/disadvantages of adding more
IP addresses. For my scenario it's just as easy to do reverse proxy with
each Node.js/Ruby server having its own port on the same IP. I can see how
RPG-CGI apps would have an easier time with multiple IP addresses.

Is that enough for you?

Depends on the number of lines. You're allowed 2k interfaces per line.

Here it involves sacrificing two doves and an unblemished young ram to

Once you have that you can add it one of two ways

Add TCP/IP Interface (ADDTCPIFC)
Start TCP/IP Interface (STRTCPIFC)

CFGTCP
1. Work with TCP/IP interfaces

What determines how many IPs can be added to an IBM i?​
