I am using jetty9.2.6. The site has ran for months without issue on the Jetty 9.2.x codes bases. I decided to audit the site to see if there were things we could do to make it more efficient. One of those things was enabling gzip. So I added the gzip filter to to my webdefault.xml file.
<filter>
<filter-name>GzipFilter</filter-name>
<filter-class>org.eclipse.jetty.servlets.GzipFilter</filter-class>
<!--
<init-param>
<param-name>mimeTypes</param-name>
<param-value>text/html,text/css,text/plain,text/xml,application/_javascript_; charset=UTF-8</param-value>
</init-param>
-->
</filter>
<filter-mapping>
<filter-name>GzipFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
I commented out the mineType filter while trying to get the gzip filter to actually gzip some content.
I turned on logging level to debug and can see the gzip filter in the chain but non of the content is gzipped.
Is there something else one must do to see content gzip'ed?
I can see these response header:
ETag: W/"KDA/WLVskAIKDA+EGdn958--gzip"
Vary: Accept-Encoding, User-Agent
Here is an example from the debug logs:
