# Developer notes

## Filter addresses

Pages obtained by filtering addresses shouldn't be cached (occasional content would just fill up the db).
To disable the caching the filter parameters might be added to 
`$GLOBALS['TYPO3_CONF_VARS']['FE']['cacheHash']['excludedParameters']` in the `ext_localconf.php` file.

## Localization

As of TYPO3 9.5.5 the language fallback to default language seems not to work properly (see
https://forge.typo3.org/issues/87950) hence all the original contents hon a page need to be available
on the language page to show up (even if they are not translated).
