Umberto, The data type is shape. The number of active layers depends on zoom level however in the map file there is a total of 39 layer definitions, with between 10 and 30 active at any one time. The queries are run only in one layer.
I have done some more work on the system and improved the operation by caching commonly used images. You can have a look at the application live if you wish - it is an infant however running live (I note it is crashed at the moment so must recycle app pool - which is in the process of being done). To see it running visit http://www.exploroz.com/Places/Find/CaravanPark.asp? ms=1 - The initial map is cached so use mouse and draw a box to run a query - you will either see the crash message or a refined result set. The application is running on a Win 2003 server so no access to Linux tools. I have been using the same .map file with the CGI interface for a few years and never had problem at all. I note that I can run the cgi mapserver process after the system has reported the .net memory allocation error. A sample of the CGI interface using the same .map file is as follows http://www.exploroz.com/cgi- bin/MapServer/MapServ.exe?mode=browse&map=e:\\inetpub\\vs126169 \\iMapPlot\\map\\ExplorOzBase.map&map_PointRef_feature=new&map_PointRef _feature_points=153.5136%20-27.4211&map_PointRef_feature_text=Adder% 20Rock&mapext=152.7636%20-28.1711%20154.2636%20- 26.6711&themode=zoomin&MapLabel=Show%20Me%20-%20Adder%20Rock% 20-27.4211%20153.5136 Any help would be appreciated.
