It's likely just an ordering problem. mod_expires runs before
mod_headers and you can't really change it any meaningful way in this
case (you can ask mod_headers to run much earlier, but then your
scripts output will overwrite it anyway)
Presumably your script issues Content-Type: text/html which is bogus
and what's seen when mod_expires runs. A short while later,
mod_headers changes the content-type.
