这是什么错误？ Net.HttpWebRequest.SetAndOrProcessResponse 中的 System.Net.InternalException
我们在 HTTP 请求期间遇到了一个非常罕见的错误：
System.Net.InternalException: System error.
at System.Net.HttpWebRequest.SetAndOrProcessResponse(Object responseOrException)
at System.Net.ConnectionReturnResult.SetResponses(ConnectionReturnResult returnResult)
at System.Net.Connection.ReadComplete(Int32 bytesRead, WebExceptionStatus errorStatus)
at System.Net.Connection.ReadCallback(IAsyncResult asyncResult)
at System.Net.Connection.ReadCallbackWrapper(IAsyncResult asyncResult)
at System.Net.LazyAsyncResult.Complete(IntPtr userToken)
at System.Net.ContextAwareResult.Complete(IntPtr userToken)
at System.Net.LazyAsyncResult.ProtectedInvokeCallback(Object result, IntPtr userToken)
at System.Net.Sockets.BaseOverlappedAsyncResult.CompletionPortCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* nativeOverlapped)
at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOVERLAP)
知道原因是什么吗？或者我们应该忽略它吗？
We are getting a really rare error during HTTP requests:
System.Net.InternalException: System error.
at System.Net.HttpWebRequest.SetAndOrProcessResponse(Object responseOrException)
at System.Net.ConnectionReturnResult.SetResponses(ConnectionReturnResult returnResult)
at System.Net.Connection.ReadComplete(Int32 bytesRead, WebExceptionStatus errorStatus)
at System.Net.Connection.ReadCallback(IAsyncResult asyncResult)
at System.Net.Connection.ReadCallbackWrapper(IAsyncResult asyncResult)
at System.Net.LazyAsyncResult.Complete(IntPtr userToken)
at System.Net.ContextAwareResult.Complete(IntPtr userToken)
at System.Net.LazyAsyncResult.ProtectedInvokeCallback(Object result, IntPtr userToken)
at System.Net.Sockets.BaseOverlappedAsyncResult.CompletionPortCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* nativeOverlapped)
at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOVERLAP)
Any idea about what's the cause? Or shall we just ignore it?

我不习惯它的异步版本，但这很可能是连接断开。
I'm not used to the async version of it, but that's very likely a dropped connection.
