[mapserver-users] Mapserver + mapcache + Google Map

[Krassovski, Misha B.]

I work on a project that has 4.5 mil points (each one is a single dot, with lat, lon),  that have to be shown on the world map.
I managed to do it with mapserver (wms) + Google map. It works fine, but very slow, so I decided to add a mapcache caching system.
Spend already a week but still can't get it work. Please take a look at error messages and my map and mapcache files.
Thank you in advance for the help!!


Here are error messages that I have.
In Firebug console:
"NetworkError: 404 Not Found - http://cdiac5.ornl.gov/cgi-bin/mapcache/gmaps/test@g/2/-1/1.png"
"NetworkError: 404 Not Found - http://cdiac5.ornl.gov/cgi-bin/mapcache/gmaps/test@g/2/-1/2.png"
"NetworkError: 502 Bad Gateway - http://cdiac5.ornl.gov/cgi-bin/mapcache/gmaps/test@g/2/0/2.png"

"NetworkError: 502 Bad Gateway - http://cdiac5.ornl.gov/cgi-bin/mapcache/gmaps/test@g/2/0/3.png"
and so on …..

In apache log:

and so on ……

If I run just the failed url from apache log, it creates 1044x1044 image with a single point in the center, and gives no error messages.
