Header for sending tag invalidation requests to Varnish.

For use with ``tag_mode: purgekeys``, default VCL supports two options:
- ``xkey-softpurge``: "Soft purge" by tags, expires relevant cache and allows for grace handling.
- ``xkey-purge``: Purge by tags, removes relevant cache immediately.

See the :ref:`FOSHttpCache library docs <foshttpcache:varnish configuration>`
on how to configure Varnish to handle tag invalidation requests.
