Absolute URLs are URLs that start with a scheme [5] (e.g., http:, https:, telnet:, mailto:) [6] and conform to scheme-specific syntax and semantics. For example, the HTTP scheme-specific syntax and semantics for HTTP URLs requires a "host" (web server address) and "absolute path", with optional components of "port" and "query".
At that moment, the relative path for the desired directory can be represented as: ./bobapples or for short: bobapples and the absolute path for the directory as: /users/mark/bobapples Given bobapples as the relative path for the directory wanted, the following may be typed at the command prompt to change the current working directory to bobapples:
[13]: §4.1 A path segment that contains a colon character (e.g., foo:bar) cannot be used as the first path segment of a relative reference if its path component does not begin with a slash (/), as it would be mistaken for a scheme component. Such a path segment must be preceded by a dot path segment (e.g., ./foo:bar). [13]: §4.2
The single slash between host and path denotes the start of the local-path part of the URI and must be present. [5] A valid file URI must therefore begin with either file:/path (no hostname), file:///path (empty hostname), or file://hostname/path. file://path (i.e. two slashes, without a hostname) is never correct, but is often used.
A program that digests and validates an XML document may later render the XML document in a different way, e.g. adding excess space between attribute definitions with an element definition, or using relative (vs. absolute) URLs, or by reordering namespace definitions.
There is no formal specification for the M3U format; it is a de facto standard.. An M3U file is a plain text file that specifies the locations of one or more media files. The file is saved with the "m3u" filename extension if the text is encoded in the local system's default non-Unicode encoding (e.g., a Windows codepage), or with the "m3u8" extension if the text is UTF-8 encoded.
The <authority> and <path-abempty> constructs in the syntax are specified in RFC 3986 also known as STD 66. Here <authority> is in essence the userinfo@host:port part of the original http URI, and <path-abempty> is the following absolute path introduced by a slash "/"; it can be empty or absent.
Adaptive streaming overview Adaptive streaming in action. Adaptive bitrate streaming is a technique used in streaming multimedia over computer networks.. While in the past most video or audio streaming technologies utilized streaming protocols such as RTP with RTSP, today's adaptive streaming technologies are based almost exclusively on HTTP, [1] and are designed to work efficiently over large ...
