Then I was hoping you could explain this snippet:

Ok, an Apache module sends and receives information through API hooks.

The CGI spec states that information is passed to the CGI app on STDIN
and in the environment, and that information is received back via
STDOUT.

What am I missing that makes them the same?

You said elsewhere in the thread that what you meant by "random" was
simply that it's not up to the module when the server process is killed.
This reminds me of two things:

1)  When people would post to clpm wanting to know why they ended up
    with two identical random integers, apparently mistaking "random"
    for "unique."  It's a frequently misused word, it seems.

2)  When Microsoft called Linux and other Open Source projects
    "potentially viral." (ie, propaganda)  If this were the case,
    the use of the word "random" would have been _ab_used.

My apologies in this.  I read the text wrong.

Good. Let's just all of us keep our terminology straight and there'll be
nothing to worry about. I may have come off sounding too arrogant in the
last post and I apologize again.  However, I would very much like to
know what Apache mod_* modules have in common with CGIs...as well as why
you chose the word "random", obviously knowing what it means,
considering your experience.
