Hi, Hi,
Is this the relevant connector config for Tomcat 5.5 server.xml? http://tomcat.apache.org/tomcat-5.0-doc/config/http.html It looks like two attributes are needed assuming you wish to add additional mimetypes: "compressableMimeType": The value is a comma separated list of MIME types for which HTTP compression may be used. The default value is text/html,text/xml,text/plain. *** Does it make sense to add KML 'application/xml'? Perhaps others? "compression": The Connector may use HTTP/1.1 GZIP compression in an attempt to save server bandwidth. The acceptable values for the parameter is "off" (disable compression), "on" (allow compression, which causes text data to be compressed), "force" (forces compression in all cases), or a numerical integer value (which is equivalent to "on", but specifies the minimum amount of data before the output is compressed). If the content-length is not known and compression is set to "on" or more aggressive, the output will also be compressed. If not specified, this attribute is set to "off". . . . <Service name="Catalina"> <Connector port="80" maxHttpHeaderSize="8192" URIEncoding="UTF-8" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" compression="on" compressableMimeType="text/html,text/xml,text/plain,application/xml" /> . . . Nice! Xml throughput is way faster.

Cool. I'm fine with that, clients can just choose to use or ignore the gml2-gzip option as they'd like. If we ever switch embedded servlet containers back to tomcat I'll look to add the default option. I would imagine the servlet container would be smart enough to figure out if the content type is already gzipped and not double compress, but then again I imagined Jetty would support gzip output.
