/**
 * The web Request class represents an HTTP request
 *
 * It encapsulates the $_SERVER variable and resolves its inconsistency among different Web servers.
 * Also it provides an interface to retrieve request parameters from $_POST, $_GET, $_COOKIES and REST
 * parameters sent via other HTTP methods like PUT or DELETE.
 *
 * Request is configured as an application component in [[\yii\web\Application]] by default.
 * You can access that instance via `Yii::$app->request`.
 *
 * @property string $absoluteUrl The currently requested absolute URL. This property is read-only.
 * @property array $acceptableContentTypes The content types ordered by the quality score. Types with the
 * highest scores will be returned first. The array keys are the content types, while the array values are the
 * corresponding quality score and other parameters as given in the header.
 * @property array $acceptableLanguages The languages ordered by the preference level. The first element
 * represents the most preferred language.
 * @property string $authPassword The password sent via HTTP authentication, null if the password is not
 * given. This property is read-only.
 * @property string $authUser The username sent via HTTP authentication, null if the username is not given.
 * This property is read-only.
 * @property string $baseUrl The relative URL for the application.
 * @property array $bodyParams The request parameters given in the request body.
 * @property string $contentType Request content-type. Null is returned if this information is not available.
 * This property is read-only.
 * @property CookieCollection $cookies The cookie collection. This property is read-only.
 * @property string $csrfToken The token used to perform CSRF validation. This property is read-only.
 * @property string $csrfTokenFromHeader The CSRF token sent via [[CSRF_HEADER]] by browser. Null is returned
 * if no such header is sent. This property is read-only.
 * @property array $eTags The entity tags. This property is read-only.
 * @property HeaderCollection $headers The header collection. This property is read-only.
 * @property string $hostInfo Schema and hostname part (with port number if needed) of the request URL (e.g.
 * `http://www.yiiframework.com`).
 * @property boolean $isAjax Whether this is an AJAX (XMLHttpRequest) request. This property is read-only.
 * @property boolean $isDelete Whether this is a DELETE request. This property is read-only.
 * @property boolean $isFlash Whether this is an Adobe Flash or Adobe Flex request. This property is
 * read-only.
 * @property boolean $isGet Whether this is a GET request. This property is read-only.
 * @property boolean $isHead Whether this is a HEAD request. This property is read-only.
 * @property boolean $isOptions Whether this is a OPTIONS request. This property is read-only.
 * @property boolean $isPatch Whether this is a PATCH request. This property is read-only.
 * @property boolean $isPjax Whether this is a PJAX request. This property is read-only.
 * @property boolean $isPost Whether this is a POST request. This property is read-only.
 * @property boolean $isPut Whether this is a PUT request. This property is read-only.
 * @property boolean $isSecureConnection If the request is sent via secure channel (https). This property is
 * read-only.
 * @property string $method Request method, such as GET, POST, HEAD, PUT, PATCH, DELETE. The value returned is
 * turned into upper case. This property is read-only.
 * @property string $pathInfo Part of the request URL that is after the entry script and before the question
 * mark. Note, the returned path info is already URL-decoded.
 * @property integer $port Port number for insecure requests.
 * @property array $queryParams The request GET parameter values.
 * @property string $queryString Part of the request URL that is after the question mark. This property is
 * read-only.
 * @property string $rawBody The request body. This property is read-only.
 * @property string $referrer URL referrer, null if not present. This property is read-only.
 * @property string $scriptFile The entry script file path.
 * @property string $scriptUrl The relative URL of the entry script.
 * @property integer $securePort Port number for secure requests.
 * @property string $serverName Server name. This property is read-only.
 * @property integer $serverPort Server port number. This property is read-only.
 * @property string $url The currently requested relative URL. Note that the URI returned is URL-encoded.
 * @property string $userAgent User agent, null if not present. This property is read-only.
