io.netty.handler.codec.http.HttpRequest
An HTTP request.
Accessing Query Parameters and Cookie

Unlike the Servlet API, a query string is constructed and decomposed by {@link QueryStringEncoder} and {@link QueryStringDecoder}. {@link Cookie}support is also provided separately via {@link CookieDecoder}, {@link ClientCookieEncoder}, and {@link @ServerCookieEncoder}. @see HttpResponse @see ClientCookieEncoder @see ServerCookieEncoder @see CookieDecoder
