RSS-Bridge ships a few options the host may or may not activate. All options are listed in the config.default.ini.php file, see Custom Configuration section for more information.

Customizable cache timeout

Sometimes it is necessary to specify custom timeouts to update contents more frequently than the bridge maintainer intended. In these cases the client may specify a custom cache timeout to prevent loading contents from cache earlier (or later).

This option can be activated by setting the cache.custom_timeout option to true. When enabled each bridge receives an additional parameter Cache timeout in seconds that can be set to any value.
