Web - URL

1 - About

An Uniform Resource Locator (URL) is a universal identifier for a resource.

It's the string that is understood by a browser when you put it in the address bar.

When the HTTP protocol is used as scheme, it's a identifier for a Web resource.

An URL was originally created to provide a method for finding an item such as a person's street address.

On a format level, the URL is a subset of an URI.

Mr. Berners-Lee, the creator of the Web’s bedrock software standards, would get rid of the double slash “//”after the “http:” in Web addresses. The double slash, though a programming convention at the time, turned out to not be really necessary, Mr. Berners-Lee explained.
