Breaking: #86492 - Removed stdWrap support for config.additionalHeaders¶
See forge#86492
Description¶
The feature to use stdWrap
for config.additionalHeaders
has been removed due to
an incompatibility with page caching.
Impact¶
stdWrap
cannot be used anymore to manipulate additional headers set via TypoScript.
Affected Installations¶
Any TYPO3 instance that uses this feature, which has been introduced with version 9.0.
Migration¶
For the time being there will be no TypoScript based solution for dynamic HTTP headers.
Consider implementing a PSR-15 middleware to add advanced logic for additional frontend response headers.
