forward method

@override Future forward(String uri, { HttpRequest? request, HttpResponse? response, })

Forward this connection to the given uri. *

• If request and/or response is ignored, the request and/or response
• of this connection is assumed.
• If uri is null, connect.uri is assumed, i.e., forwarded to the same handler.
• After calling this method, the caller shall write the output stream in then, since
• the request handler for the given URI might handle it asynchronously. For example,

• await connect.forward(connect, "another");
  

• connect.response.write("<p>More content</p>");
  

• ...
  

• • uri - the URI to chain. If omitted, it is the same as this connection.
• It can contain the query string too.
• ##Difference between forward and include
• forward and include are almost the same, except
• • The included request handler won't be able to generate any HTTP headers
• (it is the job of the caller). Any updates to HTTP headers in the included
• request handler are simply ignored.
• Notice the default implementation is connect.forward(connect, uri...).

Implementation

@override
Future forward(String uri, {HttpRequest? request, HttpResponse? response})
=> origin.forward(uri, request: request ?? this.request,
  response: response != null ? response: this.response);
