Which protocol should I use to configure Tomcat to accept proxied requests

[Hoang Dang]

In section 2 of this document: https://confluence.atlassian.com/adminjiraserver072/integrating-jira-applications-with-iis-828788154.html#IntegratingJIRAapplicationswithIIS-configureiis

It said 

HTTP/1.1 Connector

If you are using the HTTP/1.1 Connector, you will need to add the following attributes to the Connector port in Tomcat's server.xml:

proxyName="mycompany.com" proxyPort="80"

Then immediately underneath it said:

Enable AJP/1.3 Connector in Tomcat: To allow Tomcat to accept requests for JIRA from IIS, edit the conf/server.xmlfile and ensure that the AJP/1.3 Connector is enabled (i.e. not commented out). To enable the AJP/1.3 Connector in a JIRA remove the comment symbols around the following section in the conf/server.xml file:

<Connector port="8009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />

Which one do I use?  If I use HTTP/1.1 connector, what do I have to change in workers.properties.minimal file?

Please make this document more clear.

This is the content of workers.properties.minimal file. As you can see I do not know what I need to put in there if I use HTTP/1.1

# workers.properties.minimal -
#
# This file provides minimal jk configuration properties needed to
# connect to Tomcat.

#
# The workers that jk should create and work with.
#
worker.list=worker1

#
# Defining a worker named worker1 and of type ajp13.
# Note that the name and the type do not have to match.
#
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009

So are you going to use the AJP1.3 connector as shown in the documentation?

If so, according to the way I read the documentation, you do not need to add any reference for the HTTP/1.1 connector.
In reading the Apache Tomcat documentation, workers.properties are only for use with AJP connectors.

If I only want to use HTTP/1.1, do I need workers.properties.minimal file? What do I put in there for HTTP/1.1?
