Hi,
thank your for your quick answer.
I would love to have an auto refresh of the external graphics files, but I
don't need anything as smart as this.
Just a "reload_external_graphics for layer xxx" request would already be
great.
One way to achieve this is to change and reload the SLD file AND ALSO
change the graphics file names.
Is there another way ?
One funny behavior :
I have A.SLD with the same graphics file G.SVG in three rules.
I have B.SLD which is A.SLD except that the 3rd rule use H.SVG.
I load A.SLD : I see my G.SVG on the maps.
I load B.SLD : I see H.SVG wherever applicable and G.SVG everywhere else.
I change the looks of G.SVG.
I load A.SLD : I see the the new G.SVG wherever I previously saw H.SVG but
I still see the old G.SVG everywhere else.
Overoptimized ?

Re: [Geoserver-users] svg refresh
in geoserver

Hallo,
I use svg files in my SLD. I show my data on a page : everything is just
right.
Then, I make some change in my svg file. I reload my page : I still see
the
old svg (before change). I empty the browser cache : same thing. I need
to
restart geoserver to see the "new" svg.
Is there another cache level on the server side ?
Yes, GeoServer loads all the external graphics once and keeps
them in memory. The cost to reload the SVG files for each request
would make using external graphics almost impossible in a real
production environment.
We'd need a smarter cache that checks the last modification date
or the files, unfortunately the files could be also over a HTTP
connection, and there we would have to check the proper http
headers each time... long story short, doing this properly is not
trivial, would require a few days of work.
If you're interested in contributing a patch in this direction I
can show you the way in the code. Or you can have this also done
by some commercial support providers, there is a page at
geoserver.org with a list of them
Cheers
Andrea
