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.
