     12Some folders will need to be on a shared filesystem (e.g. NFS):
     13* {{{/uploads}}} (or they could be synced across e.g. using rsync)
     14* {{{/errors}}} {if these are to be viewed using Web UI)
     15* {{{/static/img/markers}}} (unless markers don't need to be customised via Web UI)
     16* {{{/sessions}}} (A better option is to use memcache for this - see {{{000_settings.py}}})
     17* {{{/databases}}} (if using dynamic tables, such as gis_layer_shapefile, otherwise these can simply be synced together, e.g. using rsync)
