Yes, but for the purposes of my needs this is fine and preferable. SEO
was in fact the reason that I started doing this.

As is, in my case. Actually, what use case is there for having Apache
reprocess the HTML output of the script?

Other possible interfaces between the application code and the web
server? Maybe you are referring to the interface with the database
server? Enlighten me, please! I am not a programmer by trade, only by
hobby.

I see. I believe that is called Dotan's Razor: a slight inaccuracy
saves a lengthy explanation.

Quite so, I though that is what you wanted. Yes, the HTML is
hard-coded into the script. I am learning to abstract and even use
object-oriented approaches, though.

That much I should be able to google when I get to it.

What I am doing _is_ trivial. However, I thank you for explaining my
options and I will take a second look at them.

Be offensive! I take no offence, I understand that your goal is to
help me. I am a hard learner: I recognize that you are teaching me the
better way, but I need convincing as to why it is better. "Bruno said
so" is good, but "saves you coding time down the line" is a lot more
convincing!
