<br><font size=2 face="sans-serif">no error...</font>
<br><font size=2 face="sans-serif">I think the problem is that my bbox
doesn't fit the grid.</font>
<br>
<br><font size=2 face="sans-serif">If I set everything (layer maxExtent
= map maxExtent = bbox .cfg and bbox tilecache_seed.py) to the same maxExtent
of my map it is working well.</font>
<br><font size=2 face="sans-serif">But the maxExtent of my map covers the
country. My layer covers the province.</font>
<br>
<br><font size=2 face="sans-serif">So I thought it was a good thing to
specify a smaller extent so there are less images requested to the server
when executing tilecache_seed.py.</font>
<br><font size=2 face="sans-serif">Does it make sense to specify a smaller
extent for the tilecache or I should not bother with that?</font>
<br>
<br><font size=2 face="sans-serif">If it makes sense please send a link
to some documentation on how set the new extent to the tilecache grid.</font>
<br>

Using Firebug, if you open the url to a requested tile in a new
<br>
tab/window, do you see an error message ?<br>
