Re: [Geoserver-users] Automatic refresh GeoServer

[Jody Garnett]

The WMS protocol has this covered with an update sequence number, clients
are expected to poll this value when connecting to the service to see if
any cached layer definitions they are working from have changed.

As for the contents geoserver has had an RSS feed that can be used to keep
track of any changes made via WFS.
- Initially used to keep a cluster of WFS's in sync it could be used by
clients also.
- The same hook is used to automatically truncate any tiles that have been
modified via WFS (so if your tile caching settings are set appropriately
downstream caches should pick up any changes as their contents are
refreshed)

The difficult part of you question is "automatically refreshing the URL" -
the URL remains the same in each case as it is the same data service, and
data product being published. The contents of the data have changed but the
service that accesses it remains available via the same URL.

Hi Diego,

just thinking out loud: depending on the WMS client you use (I would
recomment QGIS ;-) )... you could use so called 'NOTIFY' event from
withing postgres.
QGIS can use those to update a Postgis layer, but maybe you can use
something similar to update the WMS client?

Read here
http://oslandia.com/en/2017/10/07/refresh-your-maps-from-postgresql/
something about it.

Another option I can think of (if you have thousands of clients who want
their maps updated) is use this NOTIFY mechanism to call some global
message system like MQTT or so, your web clients then could maybe react
to mqtt-events?

Regards,

Richard Duivenvoorde
