[REBOL] Re: hook while downloading from html port

Scott, I think you are a bit negative about transfer rates. :)
Surely there is a way.
Here also, is an easier way to save the scheme:
write clipboard:// join {rebol [] system/schemes/http:} mold
system/schemes/http
Now open your favourite editor, paste into a new file and save.
Uh oh, now I'm into it...
Search for "read:". You have found the read function.
Now add a line after the "net-utils/net-log" line:
print join "bytes: " [port/state/num " at " now/time/precise]
Save the file and do it. Then test the change:
>> read http://www.rebol.com/

With that info it's possible to make up some progress callback so you
can make a display showing transfer rate.
You would need to add a couple of variables to the http object, eg:
total-bytes
last-transfer-time
and reset these at the appropriate time.
Mmm.. while I'm here I can see the /custom refinement.
If I ever forget the custom refinement dialect I can
look here in the source.
