* Note: Memory pool allocation. |
706 |
* Use a shorter-lived pool to reduce memory usage |
| 707 |
* A downstream keepalive connection is always connected to the existence |
707 |
* and avoid a memory leak |
| 708 |
* (or not) of an upstream keepalive connection. If this is not done then |
|
|
| 709 |
* load balancing against multiple backend servers breaks (one backend |
| 710 |
* server ends up taking 100% of the load), and the risk is run of |
| 711 |
* downstream keepalive connections being kept open unnecessarily. This |
| 712 |
* keeps webservers busy and ties up resources. |
| 713 |
* |
| 714 |
* As a result, we allocate all sockets out of the upstream connection |
| 715 |
* pool, and when we want to reuse a socket, we check first whether the |
| 716 |
* connection ID of the current upstream connection is the same as that |
| 717 |
* of the connection when the socket was opened. |
