Breaking: #97550 - TypoScript option config.disableCharsetHeader removed¶
See Issue #97550
The TypoScript flag
config.disableCharsetHeader has been completely removed
from TYPO3 Core.
This option was used to avoid sending HTTP headers of type “Content-Type” to the client. This flag was mainly used to overcome a technical limitation to override the Content-Type information back in TYPO3 v4.x.
TYPO3 now always sends the
Content-Type header to the client in the TYPO3
TYPO3 installations having this option enabled via TypoScript.
It is not needed to set this option. Even when Extbase plugins return JSON-based Responses, the Content-Type header is already modified.
In special cases, when custom headers are required, it is possible to modify the headers via a PHP-based PSR-15 middleware, or via TypoScript with “config.additionalHeaders”.
