you can ignore me. i've had a look and it was pointed out that this was a SSI problem.
i had a look at: http://apache.planetmirror.com/docs/howto/ssi.html which gives some pointers. i had SSI enabled, but it appears it wasn't turned on for the VHost that is apache.planetmirror.com - i didn't realise one has to specify stuff explicitly within vhosts, since i had this in the global part. it works now.. regards, -jason
