Turn on HTTP compressed responses in Tomcat

[jgallagher59701]

We need a ticket to turn on HTTP compressed responses in Tomcat. We had it, but it got dropped in the change to encrypted DIT
We had this:

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="1000000"
               redirectPort="8443"
               compression="force"
               compressionMinSize="2048"
               compressibleMimeType="text/html,text/xml,text/plain,text/css,text/javascript,application/javascript,application/octet-stream,application/vnd.opendap.dap4.dataset-services+xml,application/vnd.opendap.dap4.dataset-metadata+xml,application/vnd.opendap.dap4.data,application/vnd.opendap.dap4.error+xml,application/json,application/prs.coverage+json,application/rdf+xml,application/x-netcdf,image/tiff;application=geotiff"
    />

And now that's commented out and instead we have this:

 <Connector port="8443" protocol="org.apache.coyote.http11.Http11AprProtocol"
               maxThreads="150" SSLEnabled="true" >
        <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
        <SSLHostConfig>
            <Certificate certificateKeyFile="/usr/share/tomcat/conf/NGAP-CA-certificate.key"
                         certificateFile="/usr/share/tomcat/conf/NGAP-CA-certificate.crt"
                         certificateChainFile="/usr/share/tomcat/conf/NGAP-CA-certificate-chain.crt"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>

No big deal, but well, egress $$

The value of the compressibleMimeType attribute should be reviewed against the Tomcat 9 documentation on what is actually acceptable as the value.

We could put this in Jira, but let's talk about it.

Well, it's:

• Only a problem in NGAP
• Can only be tested in an NGAP deployment (ex: SIT)

[jgallagher59701]

Oh, so in the non-ngap-tagged Docker container for Hyrax compression is on?

[ndp-opendap]

That's correct

It still adds application/x-netcdf and image/tiff;application=geotiff to the list of things to compress tho

Hyrax:

And the ngap container:
