# Reload on SIGHUP
Some config values can be reloaded on SIGHUP signal.
Such parameters have special mark in tables below.
You can send SIGHUP signal to app using the following command:
```shell
$ kill -s SIGHUP <app_pid>
```
Example:
```shell
$ ./bin/neofs-http-gw --config config.yaml &> http.log &
[1] 998346
$ cat http.log
# ...

# ...
$ kill -s SIGHUP 998346
$ cat http.log
