With TSGetNet, is it possible to just get the "status code" ("200" is good,
"404" it bad, among other things)
Of a file on a webserver, *before* you download it? If it is a 404 you "bail on
the operation", in form the user "Not Found" but if it is 200, continue to
stream it?

Hi BR,
There are a series of lessons on tsNet on the LiveCode website:
http://lessons.livecode.com/m/4071/c/235433
If you are looking for an example of how to download something direct to a
file, the lesson called “How to asynchronously download via SFTP directly a
