Hi all,

I'm seeing confusing responses from our server.  I configured Tomcat to
allow resources to persist for 12 hours as per the below filter:

<filter>
 <filter-name>ExpiresFilter</filter-name>
 <filter-class>org.apache.catalina.filters.ExpiresFilter</filter-class>
 <init-param>
  <param-name>ExpiresDefault</param-name>
  <param-value>access plus 1 month</param-value>
 </init-param>
</filter>
<filter-mapping>
 <filter-name>ExpiresFilter</filter-name>
 <url-pattern>/*</url-pattern>
 <dispatcher>REQUEST</dispatcher>
</filter-mapping>

When using the OPTIONS HTTP method to make a GetCapbabilities request, I
see the expected response header value for
Cache-Control:  max-age=2682000.  However, when I send a GetCapabilities
request using the GET method, I see a value of "max-age=0, must-revalidate"
for Cache-Control.

Does GeoServer force the value for Cache-Control and, if so, is this
configurable?

Here are my specs:
Geoserver version:  2.15.2
Server version: Apache Tomcat/8.5.43

Thanks everyone.

Best,
Todd
