Response body not possible (null) if HTTP status code is 304 (not modified). #1267

Open fsilkswan opened 1 year ago

Hi there,

I've come to notice that it is not possible to deliver a response body to an arbitrary client in case the HTTP status code is set to 304 in the Response object. Client's will not receive any content, even the Route returns a String and/or the body field of the Response is set.

The other 3xx codes seem to allow a response body though.

Is there a reason why 304 has a special treatment regarding the response body?

Kind regards -Ferdinand-

MDN says "The response must not contain a body " it's the http standard https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/304
