[ka-Map-users] couple issues - maybe a cache bug

[Ravi]

Further investigation shows that even at 512x512 it fails to generate 
'some' files. I tried to set tile size to 512x512 and "tile_source" to 
"cache". My apache error logs are full of following errors.

[Thu Nov 23 11:15:18 2006] [error] [client 192.168.1.2] File does not 
exist:

Notice that in first error it is at least requesting a specific file, in 
second case it seems to be requesting a directory which seems odd to me 
but you may know better. The second type of errors are a LOT more than 
first type.

Also, after IE tries to load these files for a minute or so, I received 
"Stack Overflow Error" in IE.
