[Tilecache] A tilecache tutorial

[Adrian Zhao]

Thank Schuyler.  

I thought that TileCache is an implementation of
http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification.  Is it
right?

I am struggling with how to link WMS, WMS-C and TMS requests together by
using TileCache and my existing web client not using OpenLayers which
has some knowledge about TMS and WMS-C.  Please help.

Thanks,
Adrian

TileCache attempts to implement the recommendations described on this
wiki page and others linked to it:

    http://wiki.osgeo.org/index.php/WMS_Tiling_Client_Recommendation

The key thing is that your request bounds need to match an acceptable
grid rectangle, as defined by the service metadata. Please let us know
if this is still unclear.
