  ## openvibe.compare — reference vhost for ov-vhost-install.
  ##
--## The comparison site is served by OpenVibe.Exchange's process on 127.0.0.1:5150 (the same app, behind its own
--## name: server/http/compare-site.js). This vhost passes the name through in Host, which is what makes the request
--## the compare site's; every other name reaches Exchange's own pages. No proxy_cache: the app decides cacheability.
++## Compare now runs in OpenVibe.Compare on port 5280. Kept here so an Exchange deployment
++## cannot restore the retired shared-process target. Canonical vhost: OpenVibe.Compare/deploy/nginx/.
