[Geoserver-devel] geoserver should reload externalGraphic symbols?

[Vincent S. <sc...@sa...>]

I'm styling a point layer with several bitmap symbols. The bitmaps (png) 
reside on the same server and are referenced in the SLD with a 'file:' 
url like in:

<ExternalGraphic>
  <OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink" 
xlink:type="simple" 
xlink:href="file:/var/geoserver/styles/symbols/open_refugee_area.png"/>
  <Format>image/png</Format>
</ExternalGraphic>


I guess geoserver caches these images? Then it does so a bit 
over-enthousiastic, because when I change these bitmaps on disk, 
geoserver keeps displaying the old bitmaps, no matter how often I press 
the 'load' button in the config interface. I would expect it to render 
the new bitmap instead. Only restarting tomcat helps.

Is there some setting I can adjust to improve this behaviour, or should 
I change something in my SLD?
Or should I file a jira issue on this?
