--- features: - | Added HTTPProxyToWSGI middleware in front of the Mistral API. The purpose of this middleware is to set up the request URL correctly in the case there is a proxy (for instance, a loadbalancer such as HAProxy) in front of the Mistral API. The HTTPProxyToWSGI is off by default and needs to be enabled via a configuration value. Fixes [`bug 1590608 <https://bugs.launchpad.net/mistral/+bug/1590608>`_] Fixes [`bug 1816364 <https://bugs.launchpad.net/mistral/+bug/1816364>`_]
