Provide the setting `useCacheHash = 1` to add a cHash. This is essential for records displayed using Extbase which enforces cHash usage. .. code-block:: typoscript TCEMAIN.preview { { previewPageId = 123 useCacheHash = 1 fieldToParameterMap { uid = tx_myext_pi1[showUid] } additionalGetParameters { tx_myext_pi1[special] = HELLO } } } If `useCacheHash = 1` is not set, the `no_cache` parameter will be added just like before. .. index:: Backend, Frontend, TSConfig
