Limitations & Issues
~~~~~~~~~~~~~~~~~~~~
Ironic contains two different ways of providing an HTTP(S) URL
to a remote BMC. The first is Swift, enabled when ``[redfish]use_swift``
is set to ``true``. Ironic uploads files to Swift, which are then shared as
Temporary Swift URLs. While highly scalable, this method does suffer from
issues where some vendors BMCs reject URLs with **&** or **?** characters.
There is no available workaround to leverage Swift in this state.
When the ``[redfish]use_swift`` setting is set to ``false``, Ironic will house
the files locally in the ``[deploy]http_root`` folder structure, and then
generate a URL pointing the BMC to connect to the HTTP service configured
via ``[deploy]http_url``.
