+# 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
+# ...
