raster not showing

[didier.georgieff]

Hello,

I'm trying to setup a mapserver demo (4.4.0), based on itasca model, and
spent the whole day on something that puzzle me ;-)

- itasca works fine including raster files.

- my demo works fine except that raster files doesn't show up (single
image or tile), but i got no error message.


===> I have a sdpen.map, an adapted index.html and a sdpen_basic.html based on itasca_basic.html.

So all works fine, except 'testign' (1 TIFF file) and 'ign25' (a tile shape for TIFFs) who are blank.

I checked and tfw are in meter and in the right coordinate range. TIFF are individually viewable with
any  graphic program, and all this works like a charm under arc/info, arcview.

Did I missed an obvious option ?

Is there a simple way to have one of those TIFF showed by mapserver, to chack if thoses tiffs are valid
for mapserver ?

Any tip, idea would be welcome. Even a full solution ;-))))

===> While trying to understand my raster problem, I found something strange (to me ;-) :
if i change the layer name of one layer, without changing it in the sdpen_basic.html

  LAYER
    NAME ign25
to
  LAYER
    NAME ign25ZZZZZ

in sdpen.map but still reference to 'ign25' in sdpen_basic.html i don't have any error
on screen, and can't find error log message in httpd logs.

Is there any sort of caching problem ? Where can i get debug messages
(i have --enable-debug in ./configure)?

Thnaks in dvance for any help.
Regards.
