-Josh:

Yes, to connect the physically local computers together via hard
lines (Ethernet) or via a router.

But in my above context "closed to the Internet" would mean no
outside connection.

Hi tedd,

I may not know all the possibilities but the only way I can think of
to accomplish that would be to have a server setup in their office
with a bank of modems and have everyone call into the server.
Basically like an old school internet provider.

If the main server can be secured to your clients liking there are
ways that it can be on the net and still as safe as possible... But
obviously not as safe as hard lines being dialed in...

You'ld also have to take into account possibly long distance charges
if everyone wasn't local...

-Alex:

Many thanks -- now I need to figure what you said and how to implement it. :-)

Does this mean that my client will need a physically local server
with fire-wall software protection or can this be done in
conventional remote hosting environment with htaccess (or whatever)
directives?

I really need to understand the basics.

Thanks for your help.

Cheers,

tedd

Forget modems or other such outside access -- everything would be
done internally with computers and users being physically located
within the office's physical location.

So, could a server be set up in an office that would run
web-languages such that users in the office could access their server
and run scripts using browsers?

Cheers,

tedd

definitely yes. many online web apps we see on internet spend their
early age in incubators not connected to internet. in other terms, in
'local area networks' which use almost same set of internet standard
protocols.
