For all sorts of reasons a SCO 5.07 box (A) cannot know a direct route to
the internet. A route can be established between it and another SCO
machine's apache proxy server another LAN, which does have a route and
gateway to the internet.

How to I get local, ie from within SCO box (A) calls for http and https to
go via the external proxy server? I think I am being rather stupid here. I
assume the answer is very simple.

Many applications will look for an environment variable http_proxy (or
HTP_proxy)

e.g.
HTTP_proxy=http://proxy.example.com:8080
or
HTTP_proxy=http://usernameassword@proxy.example.com:8080

Thanks. I will go and play, but I fear the application has no such variable,
as I suspect they would not expect
or want anyone to go via a proxy for authentication reasons. What I need is
something that traps all locally derived calls to port 80 or whatever and
tunnels it elsewhere.

It sounds like you need transparent proxying
http://en.tldp.org/HOWTO/TransparentProxy-2.html

You can run a transparent proxy (e.g. Squid) in addition to your
existing Apache proxy on your default gateway machine, so long as you
can allocate separate port numbers to the Apache proxy. I'd use squid
for proxying and apache for plain ordinary web serving. YMMV.
