URL's

From Gwiki

What's in a URL?

Anatomy of a URL:

URI or (protocols): scheme specific part

http is a scheme

URI's are not necessarily protocols, they represent a location on the internet. Ex. "file"

<scheme name> : <hierarchical part> [ ? <query> ] [# <fragment>]

Where the scheme name starts with a letter followed by letters, numbers, +,-, or a period and terminated with a colon.
