This template is under construction.            

Please do not use this unfinished and/or still unreliable template.            

The {{URL}} OEIS Wiki utility template is used either to encode an unencoded URL, or to extract sections from a URL.

URL

An generic URL takes the form:

scheme:scheme-specific-part

Common Internet scheme syntax:

//user:password@host:port/path

An HTTP URL takes the form:

scheme://server.domain:port/path?query_string#fragment_id

Every URL consists of some of the following:

• the scheme name (commonly called protocol), followed by a colon (:),
• two slashes (//), then, depending on scheme,
• for http protocol, either
  • a server name (e.g. ftp, www, smtp, ...) followed by a dot (.) then a domain name, or
  • a server IP address followed by a dot (.) then a domain IP address,
• optionally: a colon (:) followed by a port number,
• the path of the resource to be fetched or the program to be run, then,
• for programs such as Common Gateway Interface (CGI) scripts, a question mark (?) followed by a query string, and
• optionally: a hash sign (#) followed by a fragment identifier.

Usage

To get an encoded URL from an unencoded URL, use

{{URL|unencoded URL}}

To extract a section from a URL, use

{{URL|unencoded URL|URL section}}

where URL section is one of

• protocol or scheme
• server.domain
• server
• domain
• port
• path
• query string
• fragment id
