Hi,
I can see from the logs that there are some OpenLayers applications reading our integrated GWC (…/geoserver/gwc/service/wms?..) by using WMS-C protocol and having “&tiled=true” while some other applications use parameter as “&tiled=yes”. I can also see that developers have copied the base URL and applications may send request including either “&tiled=yes” or “&tiled=true” also to non-cached WMS (…/geoserver/wms?)
Are “tiled=yes” and “tiled=true” just synonyms or should we try to reach the developers and tell them to use always just one of the alternatives? Situation has probably been like this for a long time so I think that using tiled=yes or tiled=true does not make any difference but I would like to know it for sure.

TLDR: tiled=true gives permission for GeoServer to return an error if GetMap request does not line up with defined tile set.
From http://wiki.osgeo.org/wiki/WMS_Tiling_Client_Recommendation
“If a request is made with tiled=true, a tiling WMS server may respond with HTTP 404 or 500 to indicate that a request fails to meet the recommendations given here.”
GeoServer will not do that, if tiles origin is not provided it will simply assume it cannot do metatling, and treat it as a simple request.
In fact tiled/tilesorigin are meant for clients that are just using simple WMS, but insist on making tiled requests, as opposed
to clients that are WMS-C aware (use GWC directly for those)
Cheers
