## 追記
|

公式サイト([該当ページ](https://www.envoyproxy.io/learn/backpressure))をチェックしてみたところ下記の様な記述がありました。
|
|
434
|
+
|
|
435
|
+
```
|
|
436
|
+
|
|

Two quick definitions, used by Envoy:
|
|
438
|
+
|
|
439
|
+
|
|
440
|
+
|
|
441
|
+
Upstream connections are the service Envoy is initiating the connection to.
|
|
442
|
+
|
|
443
|
+
Downstream connections are the client that is initiating a request through Envoy.
|
|
444
|
+
|
|
445
|
+
```
|
|
446
|
+
|
|
447
|
+
```
|

|
+
Upstream Connection Closed
|
|
450
|
+
|
|
451
|
+
What it is: When the upstream closes the connection before the response is finished sending, Envoy cannot send a complete response to the downstream.
|
|
452
|
+
|
|
453
|
+
|
|
454
|
+
|
|
455
|
+
Result: This depends on whether the downstream has started receiving data.
|
|
456
|
+
|
|
457
|
+
|
|
458
|
+
|
|
459
|
+
If it has not (i.e. the upstream disconnects quickly), the downstream connection is reset.
|
|
460
|
+
|
|
461
|
+
If it has, the downstream receives an HTTP 503 and the body text “upstream connect error or disconnect/reset before headers”
