you configure mapcache as usual and symlink the levels for the shared zoom levels. MapCache creates a directory structure in the filesystem for every tileset like <base>/<tileset>/<grid>/<zoom_level>. You can also create it by hand (watch for correct access rights) and then symlink directories from the second tileset to the first. It should look something like this: # cd <base>/<tileset1>/<grid>/; ls -ld drwxrwxr-x 3 apache apache 3896 Aug 30 2011 00 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 01 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 02 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 03 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 04 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 05 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 06 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 07 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 08 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 09 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 10 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 11 drwxrwxr-x 2 apache apache 3896 May 14 15:08 blanks # cd <base>/<tileset2>/<grid>/; ls -ld drwxrwxr-x 3 apache apache 3896 Aug 30 2011 00 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 01 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 02 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 03 drwxrwxr-x 3 apache apache 3896 Aug 30 2011 04 lrwxrwxrwx 1 root root 22 Dec 7 2011 05 -> ../../<tileset1>/05 lrwxrwxrwx 1 root root 22 Dec 7 2011 06 -> ../../<tileset1>/06 lrwxrwxrwx 1 root root 22 Dec 7 2011 07 -> ../../<tileset1>/07 lrwxrwxrwx 1 root root 22 Dec 7 2011 08 -> ../../<tileset1>/08 lrwxrwxrwx 1 root root 22 Dec 7 2011 09 -> ../../<tileset1>/09 lrwxrwxrwx 1 root root 22 Dec 7 2011 10 -> ../../<tileset1>/10 lrwxrwxrwx 1 root root 22 Dec 7 2011 11 -> ../../<tileset1>/11 lrwxrwxrwx 1 root root 22 Dec 7 2011 blanks -> ../../<tileset1>/blanks drwxrwxr-x 2 apache apache 3896 May 14 15:08 <base>/<tileset1>/<grid>/blanks This construct shares levels 5-11 between tileset1 and tileset2. _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
