And to load it back, do it, not load it.
it will look like
make object! [
..
]
and thats code to make an object, not an object itself.
(not tested if http works then, but with ftp)
and remember to save/header, 'do checks for that with a file.
Or don't and use [do load %http.r] later.
Btw nice trick for dumping is with compose:
save/header %http.r compose/only [
system/schemes/HTTP: (system/schemes/HTTP)
][Title: "my http"]
And then just [do %http.r]

Any problem in computer science can be solved with another layer of
indirection. But that usually will create another problem.
