Hi all,

Wondering if there is a way to enable caching and/or Gzip compression for REST Webdev calls? I would think that those are enabled at the Web Server level, but do we have access to those settings?

Thanks,

Oscar.

Adding more details here after some research:

It looks like on the later versions of Jetty, gzip compression is enabled via gzip.mod, and enabled via the jetty-gzip.xml or a “context xml” file. Not sure where those reside?  
[https://www.eclipse.org/jetty/documentation/9.3.22.v20171030/gzip-filter.html](https://www.eclipse.org/jetty/documentation/9.3.22.v20171030/gzip-filter.html)

In earlier versions, a gzip handler can be added to web.xml (/ignition/webserver/webapps/main/WEB-INF/web.xml); but that approach is no longer supported? Can someone confirm?
