Fallback path to search is needed because some software may keep FileName attribute and ignore FilePath attribute during file upload. Therefore, if this feature is enabled under certain conditions (for more information, see gate-configuration.md) a search will be performed for the FileName attribute.

# FrostFS HTTP Gateway configuration file
|
|
|
|
This section contains detailed FrostFS HTTP Gateway configuration file description
|
|
including default config values and some tips to set up configurable values.
|
|
|
|
There are some custom types used for brevity:
|
|
|
|
* `duration` -- string consisting of a number and a suffix. Suffix examples include `s` (seconds), `m` (minutes), `ms` (
|
|
milliseconds).
|
|
|
|
|
|
# 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/frostfs-http-gw --config config.yaml &> http.log &
|
|
[1] 998346
|
|
|
|
$ cat http.log
|
|
# ...
|
|

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