[TYPO3-mvc] Strange caching behaviour

[Frans Saris]

Hi Jan,

I don't know yet how to prevent this. But I can confirm this behaviour.

Would be great if someone could give a hint how we can prevent this.
Giving a 404 when the cHash is incorrect is not a suitable solution.

When the cHash is incorrect the parameters should be ignored.
