Access the htmx context to access the Request Headers and use the set-methods on the response.htmx
to change the Response Headers for HTMX.

.. code-block:: python
    class ItemEndpointBattery(DXEndpointBattery):
        inline_template = TEMPLATE

        @dx_put("copy/item/<int:item_id>")
        def copy(self, request, item_id):
            ...
            if request.htmx.source == 'button#copy-btn':
                messages.success(request, f"Item copied!")
                response = self.render_section(request, "copied-item", context)
                response.htmx.set_retarget(f"#copy-cat-tab")
                response.htmx.set_reswap("beforeend")
            else:
                messages.warning(request, f"Copy aborted")
                return self.render_section(request, "item", context)
