Hi Todd, Yes, I could imagine this being a reasonable feature to surface in the UI. (That said, I'm not the gatekeeper for reasonable, so this is just one opinion.) In terms of ease, I'd agree that a checkbox would be great; that said, you can set this variable in a number of ways which doesn't require a code change to GeoServer. For instance, you could run the Tomcat JVM with -DCAPABILITIES_CACHE_CONTROL_ENABLED=false. Cheers, Jim On 10/17/19 11:34 AM, Todd Jacobus wrote: > Hi Jim, > > Thanks very much for looking into this.
