..  _production-only:

Production only
~~~~~~~~~~~~~~~

If checked, this prevents any Myra Cloud cache clear request and disables all UI elements if the
application context is not :php:`Production*`. This is useful to prevent clear requests from stage
or development instances.

..  _admin-only:

Admin Only UI Elements
~~~~~~~~~~~~~~~~~~~~~~

If checked, all UI Elements are disabled for non-admin users.

..  note::
    Auto-clear hooks (page update / file list replace / cache tag flush) are not affected by this.

..  _disable-hooks:

Disable Hooks
~~~~~~~~~~~~~

If checked, all AutoClear mechanisms (page update, file list replace and cache tag flush) are disabled.

..  note::
    This is only respected by this extension's own hooks / event listeners. It has no
    effect on :php:`clearCachePostProc` hooks (or other TYPO3 hooks/listeners) registered
    by third-party extensions (e.g. EXT:news' data handler hook) - those run independently
    and are not aware of this setting.

..  _domain-blacklist:

Domain Blacklist
~~~~~~~~~~~~~~~~

A comma separated blacklist of domain names to prevent any Myra Cloud clear cache request and
disable all UI elements if TYPO3 is used from a domain in this list.

..  note::
    This does not affect the CLI command.

..  versionchanged:: 3.0.0
    Since version 3.0.0, the :php:`domainBlacklist` configuration may contain values which are
    parseable by PHP's :php:`fnmatch` function. Example: :php:`*.ddev.site`
