Breaking: #97550 - TypoScript option config.disableCharsetHeader removed¶
The TypoScript flag
config.disableCharsetHeader has been completely removed
from TYPO3 Core.
This option was used to avoid sending HTTP headers of type
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".
