Not possible to set "robots" and "canonical_link" from uncached plugins
0%
Description
Currently it is not possible to manually set "robots" or "canonical_link" from uncached (extbase) plugins. The following does not work (when uncached):
$GLOBALS['TSFE']->page['canonical_link'] = 'Lorem ipsum dolor sit amet'
$GLOBALS['TSFE']->page['robots'] = true;
$GLOBALS['TSFE']->page['no_follow'] = true;
$GLOBALS['TSFE']->page['no_index'] = true;
Also, when using the meta tag api it is not possible to set "robots" from an uncached scope (it just works for cached plugins):
$metaTagRegistry->getManagerForProperty('robots')->addProperty('robots', 'noindex,nofollow);
So the only option to set "canonical_link" from an uncached scope is using the "ModifyUrlForCanonicalTagEvent" event, which is fine itself. But regarding the "robots", the only solution seems to set it using typoscript (page.meta.robots = noindex,nofollow).
The core should be extended in the following way:
1. Add possibility to modify the "robots" tag using the meta tag api even when in uncached scope
2. Add possibility to modify the "canonical" directly ($GLOBALS['TSFE']->page['canonical_link'], or anything else) even when in uncached scope

The call flow in \TYPO3\CMS\Frontend\Http\RequestHandler::handle:
generatePageContent()- calls
processHtmlBasedRenderingSettings()- invokes
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['TYPO3\CMS\Frontend\Page\PageGenerator']['generateMetaTags']
- invokes
- calls
generatePageContent()is called before$controller->isINTincScript()
That's why uncached actions don't have any effect, since the meta-tag content has been processed already.

Okay. But for example Page Title API can be used even from an uncached scope. Shouldn’t we have the same behavior for Meta Tag API?
