I searched my WebSTAR mail folder for MTU and came across a recommendation for IP 
NetTuner from Sustainable Softworks

I downloaded it, ran it, tested HTTP upload - and guess what? It worked first time...

Thank you Anthony, and thanks to everyone on this great list!

BTW I used the default DSL "tune=up" to make it work

I think you have hit the nail on the head. NTL use Inktomi Proxies in the UK and the 
caching of images, in particular, makes life very difficult when testing. And it seems 
as though there is no "Proxy-Free" option

By contrast, BT Openworld (probably the worst Telecoms Provider and ISP in the known 
world) had no such problems, which is just as well because I believe that _all_ UK 
broadband connections are provided by BT's system - excepting cable suppliers like NTL 
and a few independent ISPs using their own hardware colocated in BT exchanges

I have reported the fault to NTL, but their email fault reporting system "Doesn't 
work" and they're hopelessly understaffed. It's just the typical UK ineptness we have 
to put up with!

Is there a debugging app that runs on Mac OS Classic? I could try verbose logging on 
the server (WebSTAR 4), but I don't know if I could interpret the results
