org.apache.commons.codec.net .URLCodec

URLCodec

public class URLCodec implements BinaryEncoder,BinaryDecoder,StringEncoder,StringDecoder(Code)

Implements the 'www-form-urlencoded' encoding scheme, also misleadingly known as URL encoding.

For more detailed information please refer to Chapter 17.13.4 'Form content types' of the HTML 4.01 Specification

This codec is meant to be a replacement for standard Java classes java.net.URLEncoder and java.net.URLDecoder on older Java platforms, as these classes in Java versions below 1.4 rely on the platform's default charset encoding.
