[OpenLayers-Users] Mapserver and Openlayers - Pink Tiles

Wed Apr 15 12:08:28 EDT 2009

The path to the 'mapserv' application should be in fact a URL, which can 
be accessed from any computer suitable for viewing the map. The path to 
your map file is a file path within the server.

i.e.

layer = new OpenLayers.Layer.MapServer("MyMap","http://myserver/cgi-bin/mapserv", {map: "c:\maps\mymap.map"} );

I have made a simple html-file in my http-root to test the openlayers/mapserver configuration (see below). The map file seems to work. I was able to generate an image with: shp2img -m mymap.map -o mymap.png (see below). When I open the example via localhost, I get a set of pink tiles and the requested map controls. I have added the location of one of the tile-images below. I also added the contents of the Mapserver map-file.
