Hi all, 

We would like to test the GeoRSS producted by Geoserver with Geowebcache in
order to control the tile expiration.

We use Geoserver (2.9) and a standalone Geowebcache (1.9) in order to
generate TMS.

In order to reseed only tiles that data have updates, we want to test
GeoRSS.

With the documentation of geowebcache
http://geowebcache.org/docs/current/configuration/layers/expiretiles.html#server-tile-expiration,
we have completed the file geowebcache.xml like this to test the tile
expiration:

   / <name>test_layer</name>
    <gridSubsets>
      <gridSubset>
        <gridSetName>EPSG:900913</gridSetName>
        <extent>
          <coords>
                <double>301614.5243302532</double>
                <double>6492166.403268518</double>
                <double>312616.500421026</double>
                <double>6499620.031302505</double>
          </coords>
        </extent>
        <minCachedLevel>12</minCachedLevel>
        <maxCachedLevel>19</maxCachedLevel>
      </gridSubset>
    </gridSubsets>
        <updateSources>
    <geoRssFeed>
     
<feedUrl>http://localhost/geoserver/wms/reflect?layers=test_layer&amp;format=rss&amp;lastupdate=${lastUpdate}</feedUrl>
          <gridSetId>EPSG:3857</gridSetId> 
      <pollInterval>600</pollInterval>
    <operation>reseed</operation>
      <format>image/png</format>
      <seedingThreads>10</seedingThreads>
     <maxMaskLevel>14</maxMaskLevel>
    </geoRssFeed>
  </updateSources> 
<wmsUrl><string>http://localhost/geoserver/wms</string></wmsUrl>
  </wmsLayer>/

But no tile is reseed after the data have been updated.
It seems that at the Geoserver GeoRSS output there is no <updated> field,
the field used by geowebcache.


Does anyone have experience with  GeoRSS in Geoserver, and/or with automatic
reseeding of tiles after a  call from geowebcache to geoserver?

Thanks, 

Aurélie
