I found one interesting prehistoric URL expression
at the last page of RFC 826. It says,
...(thanks to MOON(_at_)SCRC@MIT-MC).
That RFC was written in 19 years ago and I don't know
what was going on in ARPANET at that time.
That old expression shows some interesing points.
A. It has muliple "@" symbols.
B. All letters are capital.
C. It doesn't include any dots.
Interesting. Could some archaeologists please explain
this hieroglyph ? BTW, where and when the current version
of URL was defined ?
Thanks for your great info.
