RE: HTTP listening ports and URL questions

Kevin,

Correct me if I'm wrong.
With named virtual hosts, you only one instance, one config file.
So what if you want to take down only one of the URLs, leave the others up and running,
I was informed this can't be done.
There either all up or all down.

Paul

More commonly what is used is something called named virtual hosts and SNI, or application routing. With named virtual hosts www.abc.com points to a folder on your system and the web pages/application all run from there. www.def.com will point to another folder. Both have the same address, but by referring to them by name, apache (or nginx or iis) can decide what web page/application to serve. Application routing is just a variation of that. www.abc.com/app1 points to a folder, and
www.abc.com/app2 points to a different folder. That can be done by the web server or the framework of the application you program in. I haven't had to use odd or different ports for anything in a very long time.

Thank you for explaining that in a way I could understand. I appreciate it.

That pretty much means a landing page then? Or a complicated solution?

Let me rephrase that. The portion of DNS that web browsers use doesn't

contain port numbers. There are SRV records in DNS that can point to
ports, but only a few protocols will try and look for them.
