I was playing around with the an instant messenger link a year or so back, when I noticed that I could type "aim:[insert some stuff here]" into the address bar. I thought it was the coolest thing and tried to figure out what it was called. A few minutes later I had turned up no answers, became bored, and moved on. I was fooling with the Digital Cable box a while back and noticed a field on one of the Diag pages that had something like "ip://[some ip address]" It reminded me of the "aim:" thing and I wanted to find out what it was called but never actually got around to doing it. Today However, did a few searches on URLs and URI and found out exactly what I wanted to know....and them some. I'd known about URLs before but the only URI schemes that I was aware of were HTTP: FTP: and Telnet:. I read the RFC on URLs RFC 1630
and found out about other Schemes from WC3 http://www.w3.org/Addressing/schemes.html#CBnpbbjcfnc
and The Wikipedia
Now That I know about them here are the ones that I think are the most interesting.
AOL instant messenger- aim:
Dictionary Server Protocol- dict
Host Specific File names- file:
Lightweight Directory Access Protocol- ldap:
I'm sure many of you already knew about this, but I must ask isn't it great thing to know?
