本地环境下如何阻止Rails应用2连接ActionCable WebSocket频道

我正在开发两个Rails 7应用。在应用1中创建了ProductsChannel频道用于广播变更，关闭应用1服务器后，启动多日未开发的应用2，发现它反复尝试连接应用1的ProductsChannel，因找不到该频道持续报错，日志如下：

Started GET "/cable" for ::1 at 2023-09-21 14:57:20 +0200
  ActiveRecord::SchemaMigration Pluck (0.2ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" ORDER BY "schema_migrations"."version" ASC

我从未给应用2添加过任何频道，已确认应用1服务器未运行，也重启过应用2，但问题依旧。不想每次切换应用都重启电脑，请问如何让应用2停止尝试使用WebSocket？

• 清理浏览器缓存与本地存储：浏览器可能缓存了应用1的ActionCable订阅配置，直接清除应用2对应域名的缓存和本地存储，或用无痕模式打开应用2测试。
• 检查应用2前端代码：搜索app/javascript目录下是否存在订阅ProductsChannel的代码片段（比如App.cable.subscriptions.create相关逻辑），如果有直接删除。
• 临时禁用ActionCable：如果应用2暂时不需要WebSocket功能，修改config/cable.yml，将开发环境的适配器设为none：

  development:
    adapter: none
  

• 重启浏览器：浏览器可能残留了WebSocket连接会话，重启浏览器可清除这些残留进程，比重启电脑更高效。
