appid

The box instance includes both generic information (2) and site-specific information (appid, site, and results).

box实例同时包含了基本信息(2)和站点特定的信息(appid、site和results)。

When the demo starts the Application Table is populated with appId 0 in the running state (green light), and idle — the requests slot indicator, the little icon beside the light, is empty.

当该demo启动时，Application Table被处于运行状态(绿灯)的appId 0填充；当处于空闲状态，请求表示器(在灯旁边的小图标)是空的。
