[mapserver-users] A couple of mapcache questions

[Robert Miller]

I'm trying to get my head around mapserver after using geoserver for a 
year or so.  I'm really impressed so far with the speed and ability of 
mapserver.  I've got a layer up and running on a WMS service and it 
works just I'd like.

My question pertains to mapcache.  After a fair amount of head 
scratching, I've got mapcache serving up the tiles, but with a couple of 
issues...

1. The layer is basically a grid structure - so a bunch of black lines.  
When I load the layer in QGIS the lines disappear 5 or 6 zoom levels 
out.  I adapted the grid from WGS84 (my layer uses epsg:4269), and I 
don't really understand resolutions, so I'm thinking that might be the 
issue.  I tried tweaking the values and everything I did just turned the 
whole layer black.

2. Although the mapserver WMS service generates a transparent layer, 
webcache is sending me a layer with an opaque white background.

I've tried googling and searching the archive for an understanding of #1 
and haven't found anything.  As for #2, I don't know where to start.  So 
any help would be much appreciated.

Thanks,
Bob Miller
