[OpenLayers-Users] OpenLayers sending wrong url to TileCache?

[rtaitmilne]

Hi,

I am trying to setup a new installation of Mapserver/TileCache/OpenLayers on
top of Ubuntu Server 8.10 in baby steps.

I have a layer of highways drawing with mapserver and being cached with
TileCache(cgi).  It seems like OpenLayers is not requesting the right URL to
get the proper Tiles.  What I get is a map filled with the same tile over
and over again.  The correct tiles are there if I manually request them in
the address bar, with a URL that represents the directory structure found
under /tmp/tilecache (my DiskCache).

The first 3 URL's that OpenLayers requests all get the same image: (from
FireBug's net monitor)
http://localhost/cgi-bin/tilecache.cgi/1.0.0/segment/00/000/000/000/000/000/002.png
http://localhost/cgi-bin/tilecache.cgi/1.0.0/segment/00/000/000/001/000/000/002.png
http://localhost/cgi-bin/tilecache.cgi/1.0.0/segment/00/000/000/002/000/000/002.png

I can get 3 tiles that look like they should go next to each other when I
manually request the 3 above URL's without the "000" directories in the
path.

Is there something wrong with my configuration? Thoughts?

I am using:
MapServer 5.0.3-2
TileCache 2.0.3-1 (latest in Ubuntu 8.10 packages)
OpenLayers 2.7

Using the tilecache.html example file
openlayers html/js snip:
 <script type="text/javascript">
        var map, layer;
        function init(){
            map = new OpenLayers.Map( $('map'));
            layer = new OpenLayers.Layer.TileCache("Sask segment",
                        ["/cgi-bin/tilecache.cgi/1.0.0/"],
                        "segment",
                        {
                                projection: "EPSG:26913",
                                units: "m",
                                format: 'image/png',
                                maxExtent: new OpenLayers.Bounds(133977.89 , 
5427363.5 ,  766071.31 , 6661918.0),
                                maxResolution: 823.038307292,
                                numZoomLevels: 7,
                                transitionEffect: "resize"
                        });
            map.addLayer(layer);
            //map.setCenter(new OpenLayers.LonLat(389986, 5770768), 0);
            if(!map.getCenter()) map.zoomToMaxExtent();
        }
        ...
    </script>
