How to "Empty" GWC Layer Cache (REST) with CQL_FILTER?

Hi All,

I’m trying to work out how I can implement an equivalent to the “Empty” (cache) as found on each TileLayer… which resides here…

geoserver/geoserver/blob/43dcfbbfeee14c1e94bf6cbcdf5674af739855d6/src/web/gwc/src/main/java/org/geoserver/gwc/web/layer/CachedLayersPage.html#L34


      
              </li>                
            </ul>
          </wicket:fragment>
          
          
          
          <!-- The fragment for the seed link -->
          <wicket:fragment wicket:id="actionsFragment">
            <div class="text-nowrap">
              <a target="_blank" wicket:id="seedLink"></a> | 
              <a target="_blank" wicket:id="truncateLink"></a>
            </div>
          </wicket:fragment>
          
          <!--  The custom drop down with optgroups -->
          <wicket:fragment wicket:id="menuFragment">
            <select wicket:id="menu" class="tile-layers-page-menu-select">
              <option><wicket:message key="selectOne">Select one</wicket:message></option>
              <option wicket:id="previewLink"></option>
            </select>
          </wicket:fragment>

My issue is that once a CQL_FILTER has been configured on the layer, I can only get the cache to truncate (via REST/XML) if I provide a matching CQL_FILTER (parameter). Therefore, to empty the entire cache for a layer which might have encountered ~200 CQL_FILTER variants… I need to know what all the ~200 CQL_FILTERS are in order to be able to clear the cache.

This doesn’t seem right… and it also seems like there might be another way as the “Empty” web/action does exist… I just can’t see how to get that to work via the REST API.

Many thanks!!!

p.s. I had a lot of issues submitting JSON and ended up having to use XML. I couldn’t see anything wrong with the JSON however these comments (thanks for whoever left them) got me to step away from JSON, onto XML and finally see 200 responses geowebcache/geowebcache/rest/src/main/java/org/geowebcache/rest/service/SeedService.java at 6cf1e8cdc6082bbb0ed10a170ab0725d389fe7b1 · GeoWebCache/geowebcache · GitHub
