-/**
- * THttpResponse class
- *
- * THttpResponse implements the mechanism for sending output to client users.
- *
- * To output a string to client, use {@link write()}. By default, the output is
- * buffered until {@link flush()} is called or the application ends. The output in
- * the buffer can also be cleaned by {@link clear()}. To disable output buffering,
- * set BufferOutput property to false.
- *
- * To send cookies to client, use {@link getCookies()}.
- * To redirect client browser to a new URL, use {@link redirect()}.
- * To send a file to client, use {@link writeFile()}.
- *
- * By default, THttpResponse is registered with {@link TApplication} as the
- * response module. It can be accessed via {@link TApplication::getResponse()}.
- *
- * THttpResponse may be configured in application configuration file as follows
- *
- * <module id="response" class="System.Web.THttpResponse" CacheExpire="20" CacheControl="nocache" BufferOutput="true" />
- *
- * where {@link getCacheExpire CacheExpire}, {@link getCacheControl CacheControl}
- * and {@link getBufferOutput BufferOutput} are optional properties of THttpResponse.
- *
- * THttpResponse sends charset header if either {@link setCharset() Charset}
- * or {@link TGlobalization::setCharset() TGlobalization.Charset} is set.
- *
- * Since 3.1.2, HTTP status code can be set with the {@link setStatusCode StatusCode} property.
- *
- * Note: Some HTTP Status codes can require additional header or body information. So, if you use {@link setStatusCode StatusCode}
- * in your application, be sure to add theses informations.
- * E.g : to make an http authentication :
- * <code>
- * public function clickAuth ($sender, $param)
- * {
- * $response=$this->getResponse();
- * $response->setStatusCode(401);
- * $response->appendHeader('WWW-Authenticate: Basic realm="Test"');
- * }
- * </code>
- *
- * This event handler will sent the 401 status code (Unauthorized) to the browser, with the WWW-Authenticate header field. This
- * will force the browser to ask for a username and a password.
- *
