URL

Universal (or Uniform) Resource Locator

Contains information about how to fetch a resource from its location. For example:

• http://example.com/mypage.html

• ftp://example.com/download.zip

• mailto:user\@example.com{.uri}

• {+}file:///home/user/file.txt+ (file:////home//user//file.txt)

• http://example.com/resource?foo=bar#fragment

• /other/link.html (A relative URL, only useful in the context of another URL)

  URLs always start with a protocol (http) and usually contain information such as the network host name (example.com) and often a document path (/foo/mypage.html). URLs may have query parameters and fragment identifiers.
