Charset negotiation
Send HEAD requests to URLs
Make URLs absolute
Parse HTTP Link: header values (RFC 5988)

Usage

Language negotiation

Quality factors in the Accept-Language: header are supported, e.g.:

Accept-Language: en-UK;q=0.7, en-US;q=0.6, no, dk;q=0.8

Code:

<?php
$http = new HTTP2();
$langs = array(
    'en'    => 'locales/en',
    'en-US' => 'locales/en',
    'en-UK' => 'locales/en',
    'de'    => 'locales/de',
    'de-DE' => 'locales/de',
    'de-AT' => 'locales/de',
);
$neg = $http->negotiateLanguage($langs);
$dir = $langs[$neg];
?>

Charset negotiation

<?php
$http = new HTTP2();
$charsets = array(
    'UTF-8',
    'ISO-8859-1',
);
$charset = $http->negotiateCharset($charsets);
?>

MIME type negotiation

<?php
$http = new HTTP2();
$contentType = array(
    'application/xhtml+xml',
    'application/xml',
    'text/html',
    'text/plain',
);
$mime = $http->negotiateMimeType($contentType);
?>
