Christian,

Thank you for your pointers.  As an aside, the semicolon (e.g. EPSG;4326)
was a typo on my part and does not actually show up in code, etc.

So I’ve been doing some further experimentation and I guess I’m not seeing
some expected behavior.  I understand the rationale for the “Seed/Truncate”
functionality.  Basically, this enables you to pre-build a cache for all
possible values before any user actually requests what would be placed in
the cache the first time a tile was requested.

However, I decided to empty the cache to see how things would be cached on a
request-by-request basis rather than seeding the cache ahead of time.  Well,
I’m not seeing it cache anything!  I’ve issued WMS requests to my GeoServer
instance (with “direct integration with GeoServer WMS” enabled, and tile
caching and cache layers enabled for my layer) using various clients (e.g.
WorldWind Java client, web-browser, curl, etc.).  My expectation is that if
I submit a GetMap request like this:

http://localhost:8080/geoserver/cite/wms?service=WMS&request=GetMap&version=1.1&srs=EPSG:4326&layers=bls_unemployment_by_state_sept_2012&styles=&transparent=TRUE&format=image/png&width=256&height=256&bbox=-144.0,18.0,-108.0,54.0&tiled=true

via the web browser, or curl, or NASA WorldWind client, that I would see at
least one image show up in: C:\Program Files (x86)\GeoServer
2.2.2\data_dir\gwc\cite_bls_unemployment_by_state_sept_2012

I mean, I can see the tile pyramid built in this directory when I explicitly
seed the layer.  But why don’t I see things being cached on a per-request
basis?  Is it something with the client-side configuration (e.g. browser,
curl, etc.) telling the server NOT to cache things?

Any maybe this is a problem using the GWC built into GeoServer.  Is it
generally recommended to stand up a separate GWC Standalone instance and
have GeoServer reference that vice using the integrated option?  Are there
good instruction for setting up such an arrangement?

v/r

Ben
