[ka-Map-users] Precache problem

[Randy Page]

Hi Jan,

I have been routinely clearing my browser cache while chasing this problem,
but it hasn't helped.   

When comparing the directory structure created on the fly and by precache, I
get the exact same structure.  For example:

NC\3000000\__base__\def\t-3000l-10000\<...image files>

The only difference is the png files from precache are blank (appear to have
no layers turned on.)   

To simplify things, I am using a mapfile with only one layer, which I have
included at the end of this email.

So far I am totally baffled.

Thanks,

Randy

Randy,

Try clearing your browser cache before switching from auto-generated to 
pre-generated tiles. Also, check the location where tiles are generated 
on the fly and check if these tiles are overwritten by precache.
