これは私のチャンネル構成です:
channel-definition id="my-polling-amf" class="mx.messaging.channels.AMFChannel"endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amfpolling" class="flex.messaging.endpoints.AMFEndpoint"/propertiesserializationlegacy-collectiontrue/legacy-collectionlegacy-maptrue/legacy-map/serializationpolling-enabledtrue/polling-enabledpolling-interval-seconds4/polling-interval-seconds /properties/channel-definition
次のシナリオがあります。2 人のユーザーが、同じブラウザーを使用して同じマシンからアプリケーションにログインしますが、インスタンスは異なります。ユーザーの 1 人がログアウトし、最終的にチャネルが切断された場合、2 番目のユーザーは、障害ハンドラーでこのメッセージ「The client has no active subscriptions over endpoint 'my-polling-amf'」メッセージを受け取り、切断して再接続します。ただし、ユーザー 1 が firefox を使用し、ユーザー 2 が IE を使用しているなど、両方のユーザーが異なる種類のブラウザーを使用している場合は正常に動作し、奇妙なことは何も表示されません。
例外は次のとおりです。
