Dear all,

I've just started working to display my images (TIF topo maps) using a =
tiled index. When I try to load the map with one of the tiles in my view =
extents, I see the following in place of the webpage, as plain text:

Content-type: text/html

... the rest of the source...

My map file defines the layer as:
LAYER
  NAME topo
  TILEINDEX topo_250k_index
  TILEITEM SHEET_NAME
  STATUS DEFAULT
  TYPE RASTER
  CLASSITEM "[pixel]"
  CLASS
     EXPRESSION ([pixel] > 0)
  END
  PROJECTION
   "proj=3Dlatlong"
  END
 END

If I move to an area for which no TIF file exists in the directory, I =
get the following text just above the text shown above:
ERROR 4: `c:\inetpub\wwwroot\maps\../data/ab/82P.tif' does not exist in =
the file system,
and is not recognised as a supported dataset name.

This leads me to believe the tile process is working correctly, having =
recognized which files are available and which are not, but something in =
the way the webpage is being processed. Any suggestions?

Chris
