| // 4.10.22.6 URL-encoded form data |
| // To decode application/x-www-form-urlencoded payloads, the following algorithm should be used |
| // This algorithm uses as inputs the payload itself, payload, consisting of a Unicode string |
| // using only characters in the range U+0000 to U+007F; a default character encoding encoding; |
| // and optionally an isindex flag indicating that the payload is to be processed as if it had |
| // been generated for a form containing an isindex control. The output of this algorithm is a |
| // sorted list of name-value pairs. If the isindex flag is set and the first control really was |
| // an isindex control, then the first name-value pair will have as its name the empty string. |
| // Which default character encoding to use can only be determined on a case-by-case basis, but |
| // generally the best character encoding to use as a default is the one that was used to encode |
| // the page on which the form used to create the payload was itself found. In the absence of a |
| // better default, UTF-8 is suggested. |
| // The isindex flag is for legacy use only. Forms in conforming HTML documents will not generate |
| // payloads that need to be decoded with this flag set. |
| // |
| // Let strings be the result of strictly splitting the string payload on U+0026 AMPERSAND |
| // characters (&). |
