Use of Apache for Remote Control -
First of all, I am new to Apache, so forgive me for asking a fairly general
question.
I hope this is the right forum.
*****************************************************************%
My question:
I was wondering if I could use Apache to act as the server for a remote
interface to other devices.
Basically, I would like to control various environmental controls in my
house via the web.
I have developed websites(HTML pages, etc.) before so that part of the
mechanics is easy.
My intent is to use Python to send data to my serial port. Running Python
programs when I am at the keyboard is not an issue, but if I wanted to
initiate them through a website, that's where I am lost.
Any assistance on this matter would be appreciated.

I am a newbie on this one(just starting out). I have Mandrake Linux 8.1 but
I do not know which version of Apache that comes with it. I will use which
ever Linux distribution and Apache that is appropriate.

That is exactly what happens.

You look at some of the references I sent. In the first two pages of
google responses there were several introductory tutorials on using CGI
with python. If you have specific questions after reading those, post
again.

In response to Joshua's comments at the bottom of this message:
Sorry for being so "dense" about this; maybe if I try to put your
"thoughts" into my words, it might help.
So, I am at a remote location sitting at my workstation(my web client) and
I access my webserver running Apache, which renders my index.html page(lets
assume that the page has some data entry fields).
Now, if I initiate a CGI request(?), I can have the data from my form past
to a (as an example a Python program) program. The program would execute
and if there is data that needs to be communicated back, the program could
send that to Apache, which would in-turn, renders it to my client.
How did I do?

Maybe I miss understood the last sentence. Was the last word "client"
supposed to be "server"?

you can -and I know some examples in perl, php so it should be possible
in python too,
and probably there is an adequate python group or mailing list

There are several ways to run python programs through apache, including
special modules that do this. However, since your requirements seem
rather basic and you are just getting started, I highly recommend you
simply use the Common Gateway Interface (CGI). This is a standard
specification for how external programs should interface with a web
server, and it will work in pretty much every web server. It simply
defines how to pass data from a web form to a program, and how to return
data from the program to the web client. For details on how to configure
apache to use cgi:
http://httpd.apache.org/docs/howto/cgi.html
For details on learning to use CGI, there are tons of references.
Google is always a good starting point:
http://www.google.com/search?q=python+cgi
Or you can look at the basic CGI specification:
