 Currently, JuiceFS S3 Gateway's cache refresh strategy involves forcibly updating the in-memory cache every 5 minutes (certain operations also trigger cache update operations). This ensures that configuration changes take effect within a maximum of 5 minutes in a multi-server setup. You can adjust this time by using the `--refresh-iam-interval` parameter. If immediate effect on a specific gateway is required, you can manually restart it.
 
+### Generate a pre-signed URL
+
+The JuiceFS S3 gateway supports the use of the `mc share` command to manage the pre-signed urls of objects on the MinIO bucket for downloading and uploading objects.
+
+Please refer to the `mc share` usage help document [here](https://min.io/docs/minio/linux/reference/minio-mc/mc-share.html#description).

 ### Bucket event notifications
 
 You can use bucket event notifications to monitor events happening on objects within a storage bucket and trigger certain actions in response.

 目前 JuiceFS S3 网关的缓存刷新策略是每 5 分钟强制更新内存缓存（部分操作也会触发缓存更新操作），这样保证多机情况下配置生效最长不会超过 5 分钟，可以通过 `--refresh-iam-interval` 参数来调整该时间。如果希望某个 S3 网关立即生效，可以尝试手动将其重启。
