<br>
<br><font size=2 face="sans-serif">I agree that I should get en error.
So, that means that there is no error with Openlayers. Probably because
it is not trying to load the tiles. The behavior was like there is a min
or maxResoltution applied. But there is not..</font>
<br>
<br><font size=2 face="sans-serif"> I changed the extent of the layer
and the BBOX of the tilecache.cfg and now it is working. But I need to
understand what went wrong.</font>
<br><font size=2 face="sans-serif">I'll do more research. I really need
to set the extent as small as possible otherwise a lot of useless request
are sent to the server.</font>
<br>
<br><font size=2 face="sans-serif">Thanks for your help,</font>

I should say that tilecache_seed.py gave no errors and there is nothing
wrong in the apache logs. The image are created but don't show up in OL.</font><font size=3>

Hello,</font><font size=3> </font><font size=2 face="sans-serif"><br>
I read several posts on bbox and maxExtent settings but I still can't make
tilecache works.</font><font size=3> </font><font size=2 face="sans-serif"><br>
I'm confuse with maxExtent, maxResolution and BBOX of OpenLayers mapOptions,
OpenLayers layer definition, tilecache.cfg and tilecache_seed.py.</font><font size=3>
</font><font size=2 face="sans-serif"><br>
<br>
I need help for clarifying this please.</font><font size=3> </font><font size=2 face="sans-serif"><br>
Below are the different settings.</font><font size=3> </font><font size=2 face="sans-serif"><br>
thanks</font><font size=3> </font><font size=2 face="sans-serif"><br>
Steve</font><font size=3> </font><font size=2 face="sans-serif"><br>
