+ * 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.
