NO1.Connection reset by peer: socket write error

Connection reset by peer: socket write error

這個跟數據庫沒有關係，當客戶端發出請求（request）後，如果還沒有完全獲得服務端的響應（response），客戶端與服務器段的連接斷開（例如斷網、按了“停止”按鈕、或者客戶端瀏覽器關閉等），服務器端就會拋出此Exception。

Causes and solutions

This exception occurs when a client made a request, and before receiving the full response, either of the following happened:

1. client's browser has been closed.
2. client's connection has been disconnected.
3. client presses the stop button.

This exception is normally harmless. It does not seem possible to trap this exception with J2SE.

③：瀏覽器端按了Stop
