Alireza,<br><br>You should ensure you don't accidentally have multiple tilecache.cfg's on your system (maybe reading from one with the wrong metatile setup), and if you still have troubles then post your tilecache.cfg (and your tilecache version) so we can see what is misconfigured.<br>

Hi fredj<br>
<br>
Yes. I have done exactly same as you say.<br>
<br>
But are you using tilecache_seed.py code to seed? if yes, look at the
output screen, you see that tiles are generated one by one..<br>
in my case, each tile takes 1 second to generate and we have like 40
layers in our map file..so I know it needs high computing power to send
each request seperately to tilecache...I was hoping that
tilecache_seed.py could jump another 11 tiles and request like 1 - 12 -
23 - 34 - 45 ....<br>
because when it calls for 1, it generate all 121 tiles around it...when
it calls 12, it generate all tiles around 12...and so on..<br>
so it doesn not need to call for: 1-2,3,4,5,6,7,8..........<br>
<br>

Hi,<br>
<br>
The meta tiling system works for me with the trunk version [1].<br>
Make sure you have the:<br>
metaTile=true<br>
metaSize=11,11<br>
in your layers options.<br>
Meta tiling is off by default even if you have a metaSize.<br>
<br>
Regards,<br>

PS: lucky you; I have more that 9'000'000 tiles in my last level :-)<br>
