What is the difference between a URI and a URL?
Created May 4, 2012
Tim Rohaly URLs are a subset of all URIs.
From RFC 2396 "Uniform Resource Identifiers"
(http://www.faqs.org/rfcs/rfc2396.html):
The term "Uniform Resource Locator" (URL) refers to the subset of URI that identify resources via a representation of their primary access mechanism (e.g., their network "location"), rather than identifying the resource by name or by some other attribute(s) of that resource.See the RFC for more detail.
