+-- |Class of maps from 'Host' to 'ResourceMap' to provide name-based
+-- virtual hosts.
+--
+-- Note that Lucu currently does not implement neither RFC 2817
+-- connection upgrading (<http://tools.ietf.org/html/rfc2817>) nor RFC
+-- 3546 server name indication
+-- (<http://tools.ietf.org/html/rfc3546#section-3.1>) so you won't be
+-- able to host more than one SSL virtual host on the same port
+-- without using wildcard certificates
+-- (<http://tools.ietf.org/html/rfc2818#section-3.1>).
