tsnetGetFile() example using HTTP?

Thanks Charles. I probably won't get all the way back into this until 
Monday, just FYI.

Also, HostM support has just given me an HTTPS tsnetGetFile download 
example stack. I tried it and my initial test worked! I still have some 
experimenting to do with it to find out which tsnetGetFile() settings 
are required for my case and which ones aren't, but the initial outcome 
is a great encouragement. (I'll be asking them if I can upload a mod of 
it to the livecodeshare site.)

Although I've been developing software since the 70s (and maybe because 
I have been), I still don't know my HTTP headers well at all. That 
spills over into not knowing exactly what tsnet settings to use in 
certain cases. I'm pretty sure that has been a large factor in my 
current challenge.

I'm using LC 9.6.0 on macOS 10.13.6 (my main dev machine) and up 
(Mojave, Catalina).

Thanks again -
Phil

Are you saying I can probably just change the protocol to HTTP and it will likely work? I'll try it when I'm not so bleary-eyed (it's almost 2 AM here in the US Pacific Northwest).

I have had limited success using FTP but it consistently fails (in my situation at least) when files are bigger than 200-300 MB (depending I guess on network traffic at that moment, or ???).

In my real-world situation I can't do that. My actual downloads are binary files that can be over 1 GB. I need to download them as files to the local disk, so for me 'tsnetGet' is out.
