[gdal-dev] caching & spatial indexing of shapefiles?

Hi there,

the documentation gave me no real answer to the question if there is
something like a caching mechanism for feature request. If I request a
feature, is this read from disk every time or somehow cached?

Another thing I could not find out is how I can activate spatial
indexing for shape files - the documentation says I should execute the
following SQL command: CREATE SPATIAL INDEX ON tablename [DEPTH N]
But what is tablename and how do I know if the spatial index is created?

Thanks in advance,
