Mapserver caching and map generation

[Stephen Woodbridge]

Ramesh,

This has been discussed quite extensively of late. Mapserver does not do 
caching at all. Every mapserver request will generate a new image. If 
you want to do caching, you might look at ka-map which creates a tile 
cache and serves the tiles if they exist or generates them if they do 
not. It is an AJAX client that uses mapserver on the back-end and looks 
like google.
