[TYPO3-dev] Internal redirect creates cHash Exception

[Johannes Mueller]

One way to solve the issue could be to add the path to
cHashExcludedParameters in your production configuration.
Install tool -> all configuration -> FE -> Add the url get param you want
to allow to cHashExcludedParameters
This leads to avoidance of cHash validation for the specific path
structure. I'm definetely not sure if this is the best way to go, but it
shall fix the issue :>
