[Tilecache] A tilecache tutorial

[Adrian Zhao]

Let me try to re-phrase it to see if it helps.  

If I send a WMS GetMap call to a WMS server which has a TileCache
installed.  How this request being served using TileCache?  I know that
image is generated on the fly for most WMS servers without TileCache.  

What I am trying to get is that if I don't use OpenLayers and I don't
want to change my client side code but still want to use tiles generated
by TileCache installed on my GeoServer.  

Thanks,
Adrian

I'm not sure what the question is, but in TileCache a tile is a tile
is a tile. Doesn't matter if a tile was generated via TMS or WMS-C or
it was pre-cached -- if it is requested by any method, it will be
reused.
