Thanks for this code. I tested it but it just returns ok. Also I just tried surfing with Safari
and that is working ok now too. I have a feeling it might crop up more when the server load is
higher (it's amazing that my server load gets high though ... i have a dual xeon with 3gb ram and
a raid array). Could you please send me the patch ... I'm capable of updating the mod_interchange
code (I think ;).
