Are all parts of the mapcache.xml required, i.e. source, cache, grid, etc?  I have MapServer running as a cgi script on Apache and I want to add MapCache in order to have cached tiles written to and read from an S3 bucket.  There are hundreds of .map files on the server machine.  The current urls look like

Https://<Https://myMapServer.our>mapserver.our<Https://myMapServer.our>organization.com/?map=/path/to/example.map&otherparams

Do I need to create a mapcache.xml with anything more than a source with http and a cache, a la

<mapcache>
<source name="map-server" type="wms">
<http>
<url>https://mapserver.ourorganization.com</url>
<connection_timeout>30</connection_timeout>
</http>
</source>
<cache name="s3" type="s3">
<url>https://mybucket.s3.amazonaws.com/tiles/{tileset}/{grid}/{z}/{x}/{y}.{ext}</url>
<headers>
<Host>mybucket.s3.amazonaws.com</Host>
</headers>
<id>XXXXXXXXXXXXXXX</id>
<secret>foobaregrwq1235234532/3245234sadgfwevsd</secret>
<region>us-east-1</region>
<operation type="put">
<headers>
<x-amz-storage-class>REDUCED_REDUNDANCY</x-amz-storage-class>
<x-amz-acl>public-read</x-amz-acl>
</headers>
</operation>
</cache>
</mapcache>

?

Thanks,
Rob
