## Notes

- send() will wait for the request to be completed synchronously; the underlying layer reuses the process-level I/O runtime.
- The HTTP client pool is enabled by default, and clients are grouped and reused according to proxy and redirection policies; a single timeout does not participate in the pool key and will still take effect according to this request.
- Requests that enable `cookie_store(true)` will not enter the shared client pool, and the cookie is only retained in this sending and redirection link.
- You can view the number of pool entries, hits, eliminations, creation failures and slow calls through `BT.stats().http`.
