know how to debug this kind of thing. Alternatively, could libcurl be
getting tripped up on something?

Enable the rewrite log and check for errors. Read the mod_rewrite docs
if you need help.
I enabled logging (tried at level 1, 2, and 3). The first request (the
working one) shows up fine; the second request, the one that is failing,
never gets logged. It looks like, for whatever reason, the request is
not getting passed to mod_rewrite.
Where can I look next?
Thanks.
