Review Comment:
```suggestion
LOG.warn("IOException", e);
```
`error` with exception stacktrace panics, a client connection io error does
not deserve that.
Currently, the handling of `sendResponse` is not consistent. I checked the
code, and found no `IOException`. We probably should revise and figure out how
to handle client connection error in a consistent way.
