Hi,
I tried both ways of enabling gzip compression for JSON and js (and others). I can't see it actually working. The GzipFilter method from the web.xml sample seems to be deprecated with a warning of "it is bug ridden" ... But then in a browser debugger I cannot see it actually zipping anything.
I trief to enable this in my BaseX 9.1.2 instance using
<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/xml,text/ecmascript,application/xhtml+xml,application/json,application/javascript,image/svg+xml</param-value> </init-param> </filter> <filter-mapping> <filter-name>GzipFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
The GzipHandler method seems to get loaded but then also in a browser debugger I cannot see it actually zipping anything.
For the GzipHandler the documentation https://www.eclipse.org/jetty/documentation/current/gzip-filter.html talks about when it actually gets invoked and mentions:
* No content-encoding is specified by the resource
I found no way to not specify an encoding for whatever I return in RESTXQ. If I don't specify anything it's UTF-8. it shows up as "; character-set=UTF-8"I did not find a way to specify no encoding. Maybe unrelated but perhaps that is a problem.
I modified webapp/WEB-INF/jetty.xml like this so it uses the GzipHandler (copied from the current jetty distribution):
<Configure id="Server" class="org.eclipse.jetty.server.Server"> <!-- Default connector. The Jetty stop port can be specified in the .basex or pom.xml configuration file. --> <Call name="addConnector"> ... </Call> <Call name="insertHandler"> <Arg> <New id="GzipHandler" class="org.eclipse.jetty.server.handler.gzip.GzipHandler"> <Set name="minGzipSize"><Property name="jetty.gzip.minGzipSize" deprecated="gzip.minGzipSize" default="2048"/></Set> <Set name="checkGzExists"><Property name="jetty.gzip.checkGzExists" deprecated="gzip.checkGzExists" default="false"/></Set> <Set name="compressionLevel"><Property name="jetty.gzip.compressionLevel" deprecated="gzip.compressionLevel" default="-1"/></Set> <Set name="inflateBufferSize"><Property name="jetty.gzip.inflateBufferSize" default="0"/></Set> <Set name="deflaterPoolCapacity"><Property name="jetty.gzip.deflaterPoolCapacity" default="-1"/></Set> <Set name="syncFlush"><Property name="jetty.gzip.syncFlush" default="false" /></Set>
<Set name="excludedAgentPatterns"> <Array type="String"> <Item><Property name="jetty.gzip.excludedUserAgent" deprecated="gzip.excludedUserAgent" default=".*MSIE.6\.0.*"/></Item> </Array> </Set>
<Set name="includedMethodList"><Property name="jetty.gzip.includedMethodList" default="GET" /></Set> <Set name="excludedMethodList"><Property name="jetty.gzip.excludedMethodList" default="" /></Set>
</New> </Arg> </Call> </Configure>
I hope there is a way to get this to work.
Best regards
