Yes, using mod_deflate.c. In /awips2/httpd_pypies/etc/httpd/conf/httpd.conf:

SetOutputFilter DEFLATE
<IfModule mod_deflate.c>
  DeflateFilterNote Input instream
  DeflateFilterNote Output outstream
  DeflateFilterNote Ratio ratio
  LogFormat '%t "%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate
  CustomLog logs/compression_log deflate
</IfModule>

and compression stats are logged
to /awips2/httpd_pypies/var/log/httpd/compression_log

Unidata CAVE for Linux is run with default command line options "-alertviz
-component thinclient" since July 2015, and I have disabled the JMS
connection functionality in the connectivity preferences dialog.

Yes, the Unidata build supports all of this.

Some users have reported success connecting NWS CAVE to Unidata EDEX, but
such use is not supported by either Unidata or NWS.
