Mapserver caching and map generation

[Ramesh Karra]

Thanks for the quick reply stephen,

So, the following entries in the map file are not used by the mapserver?

WEB
    IMAGEPATH '/ms4w/tmp/ms_tmp/'
    IMAGEURL  '/ms_tmp/'
END

Anyway, I will post the question to ka-map list.

Thanks again
Ramesh
