What is wrong on this cod system?

[kubajs]

Hi,

i create thise mime type on my web server:
text/x-co-desc for *.cod files

i create example cod file named supermario.cod:
COD-Name: SuperMario
COD-URL: http://wap.wapstranky.cz/supermario.mid
COD-Install-Notify: http://www.wapstranky.cz/nic.php?file=mario
COD-Type: audio/mid
COD-Size: 4328
COD-Description: For testing COD delivery system and polyphonic ringtones.
COD-Vendor: WapStranky.CZ
COD-Next-URL: http://www.wapstranky.cz/nic.php?file=mario
COD-NextURLatError: http://www.wapstranky.cz/nic.php?file=marionepoved

But if i tested this in Nokia Mobile Internet Toolkit and Nokia 6590 Simulator, this cod file was interpreted as text!

What is wrong?

test url: http://wap.wapstranky.cz/cod/supermario.cod

Thanks for answer

Jakub

[apiq]

in my apache configuration, I put:
AddType text/x-co-desc cod

can you tell me what is the format of nic.php or the COD-Install-Notify?
I still confuse about that.
TIA
