John -
 
Each CGI request to MapServer is a completely new request, that behaves
as if it were the first MapServer request to that machine ever - it is
completely stateless, and all changes to data and indexes take effect
immediately.
 
If you are using caching software on the client or on your server, you
can modify that behavior, but that should come as no surprise.

Hi, 

If you have an existing raster mosaic and you try to add an image using
gdalwarp and then run gdaladdo to rebuild the internal overviews, then
do these operations affect the display of this raster mosaic within
mapserver while they are running and after these operations complete
will any future requests for this mosaic include this newly added image
with its newly revised overlays or would apache have to be restarted? 

Also I have the same question for rerunning gdaltindex against an
existing .shp file ( i.e. gdaltindex doq_index.shp doq/*.tif ) in order
to add a new image will this operation affect ongoing displays against
this shapefile within mapserver while they are running and after this
operation completes will any future requests for this .shp include this
newly added image or would apache have to be restarted?


Thanks,
