The paragraph at the end is important:
> If a request is made using any of the above parameters, the request will
be passed to GeoServer, unless a parameter filter has been set up, in which
case GeoWebCache will process the request.
You need to add a parameter filter to let GWC know that it can cache based
on that parameter and what values to allow.
You can check the headers of the response to see if GWC handled it. If you
see geowebcache-cache-result then GWC handled the tile, it may have a value
of HIT or MISS. If you make the same request again, then the result should
always be HIT if caching is working.
You might also run into issues with girdset alignment if you are using
anything other than the standard WGS84 or Web Mercator gridsets. The
client may not know how to read the gridset info from the capabilities doc
which could lead to misaligned tile requests unless you configure the
client manually. If you want to enforce the use of caching, use the GWC
endpoints rather than Direct Integration. If anything goes wrong then,
you'll just get an error rather than an otherwise correct response that
bypasses the cache.
