Please can the following snippet be included in Confluence's conf/server.xml:

<!--
              <Connector port="8009" redirectPort="443" enableLookups="false" protocol="AJP/1.3" URIEncoding="UTF-8"/>
        -->

Rationale: almost all production Confluence instances are going to have a web server in front. Most of those will be Apache. If you're using Apache, mod_proxy_ajp is nicest because it transmits the SSL state and host headers to Tomcat correctly. So a lot of admins are going to want the snippet above at some stage, and wouldn't it be nice if, like in JIRA's conf/server.xml, it was just there to uncomment?
