Problematic cHash handling by TYPO3
0%
Description
Contrary to TYPO3 8, it's not possible to disable the cHash on a per page basis any more in TYPO3 9/10 and if the cHash is wrong, TYPO3 returns an error page instead of serving the page content without creating a cache entry.
Problem:
When redirecting in a shop to external payment servers at the end of the checkout, the payment providers will redirect the customer back to the shop after they processed the payment. These redirects will contain additional parameters rendering the cHash invalid and TYPO3 returns an error page. Current workaround is to remove the cHash from the URLs manually with the regex to avoid errors.

cHash is added automatically, in case provided URL params cannot be mapped statically. The result can be adjusted by either
- using "aspect mappers" for those variables in a route, see https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/Routing/AdvancedRoutingConfiguration.html#aspects, or
- excluding those URL params from
cHashcalculation, see https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/CachingFramework/Index.html#confval-excludedParameters
Aspect mappers can be configured per page (with their enhancer config section), but the cacheHash.excludedParameters setting is applied globally.

Both doesn't help because the parameters sent by the various payment gateways are not known upfront.
Neither aspect mappers nor excludes does help in that case, only entirely removing the cHash from the URL that is used by the payment gateways to redirect the customer back to the TYPO3 page.
