mutate in interface HttpRequest<T>

Returns:

The mutable request

getAttribute

@NonNull
public java.util.Optional<java.lang.Object> getAttribute(java.lang.CharSequence name)

Description copied from interface: AttributeHolder

Obtain the value of an attribute on the HTTP method.

Specified by:

getAttribute in interface AttributeHolder

Parameters:

name - The name of the attribute

Description copied from interface: PushCapableHttpRequest

Check whether HTTP2 server push is supported by the remote client. Only HTTP2 clients that indicate support through HTTP2 settings have this method return true.

Specified by:

isServerPushSupported in interface PushCapableHttpRequest<T>

Returns:

true iff server push is supported.

serverPush

public PushCapableHttpRequest<T> serverPush(@NotNull
                                            HttpRequest<?> request)

Description copied from interface: PushCapableHttpRequest

Initiate a HTTP2 server push for the given request. The information from the given request (i.e. path, headers) will be passed on to the client immediately so that it does not send the request itself. Then, the given request will be handled as if it was initiated by the client, and the response will be passed back to the client.

This method mostly follows the semantics of JavaEE javax.servlet.http.PushBuilder. This means most of the headers of this request are copied into the push request, and the referer is set. To override this behavior, add a corresponding header to the request passed as the parameter of this method: those headers take precedence.

Security note: The Authorization header and other headers not excluded by the above paragraph will be copied and sent to the client as part of a HTTP2 PUSH_PROMISE. Normally, this is fine, because the client sent those headers in the first place. But if there is an intermediate proxy that added a header, this header may then leak to the client.

Specified by:

serverPush in interface PushCapableHttpRequest<T>

Parameters:

request - The request to respond to using a server push.

Returns:

This request.

initCharset

protected java.nio.charset.Charset initCharset(java.nio.charset.Charset characterEncoding)

Specified by:

initCharset in class AbstractNettyHttpRequest<T>

Parameters:

characterEncoding - The charactger encoding

Returns:

The Charset
