Since 2014, W3C recommends to use only ampersand as query separator. [7] The form content is only encoded in the URL's query string when the form submission method is GET. The same encoding is used by default when the submission method is POST, but the result is submitted as the HTTP request body rather than being included in a modified URL. [8]
URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI. Although it is known as URL encoding , it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource ...
This article lists the character entity references that are valid in HTML and XML documents. A character entity reference refers to the content of a named entity. An entity declaration is created in XML, SGML and HTML documents (before HTML5) by using the <!ENTITY name "value"> syntax in a document type definition (DTD).
Numeric character references (e.g. [ or [) should not be used in external links because the ampersand character (&) has a special meaning in a URL. In excessive cases, an automatic percent encoder such as the one at W3 Schools (use the second JavaScript form under "URL Encoding Functions") is probably the simplest solution.
When present, this indicates that the data content of the URI is binary data, encoded in ASCII format using the Base64 scheme for binary-to-text encoding. The base64 extension is distinguished from any media type parameters by virtue of not having a =value component and by coming after any media type parameters.
A URL is a specific type of Uniform Resource Identifier (URI), [2] [3] although many people use the two terms interchangeably. [ 4 ] [ a ] URLs occur most commonly to reference web pages ( HTTP / HTTPS ) but are also used for file transfer ( FTP ), email ( mailto ), database access ( JDBC ), and many other applications.
SGML derived the use from IBM Generalized Markup Language, which was one of many IBM-mainframe languages to use the ampersand to signal a text substitution, eventually going back to System/360 macro assembly language. In the plain TeX markup language, the ampersand is used to mark tabstops. The ampersand itself can be applied in TeX with \&.
A numeric character reference in HTML refers to a character by its Universal Character Set/Unicode code point, and uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form. The x must be lowercase in XML documents.
