returning HTTP error code

[Helios de Creisquer]

Hi !

I've got a mod_perl script calling an external program which
use much memory. And I would like to send a 503 instead of
calling this external program when there is less than xxxMB
of memory free.

Is mod_perl provides this ability to decide to send 
an HTTP return code or another ?

Thx for your answers...

Cheers.
