∟URL Encoding Variations

This section describes variations of URL encodings: RFC 3986 URI Encoding, application/x-www-form-urlencoded Encoding, RFC 1738 URL Encoding.

Several variations of the URL encoding are used today:

RFC 3986 URI Encoding

RFC 3986 URI Encoding is defined in RFC 3986 - "Uniform Resource Identifier (URI): Generic Syntax" at http://tools.ietf.org/html/rfc3986. See the previous section for details.

application/x-www-form-urlencoded Encoding

application/x-www-form-urlencoded Encoding is the same as RFC 3986 URI Encoding except that:

Space characters ( ) are replaced by plus sign characters (+).

RFC 1738 URL Encoding

RFC 1738 URL Encoding is defined in "RFC 1738 Uniform Resource Locators (URL)" at http://tools.ietf.org/html/rfc1738.

RFC 1738 URL Encoding is the same as RFC 3986 URI Encoding except that:

Characters outside the URL character set are not required to be converted using UTF-8 schema. Any other schemas can be used to convert characters to byte sequences. Then each byte of the sequence is encoded as %xx, where xx is a pair of hexadecimal digits representing that byte.

RFC 1738 URL Encoding

RFC 1738 URL Encoding is defined in "RFC 1738 Uniform Resource Locators (URL)" at http://tools.ietf.org/html/rfc1738.
