Easier solution: use LImitRequestBody, but have a perl handler that
sets a custom response text for 413's as appropriate.
something like:
sub handler {
my $r = shift;
if ($r->uri =~ /abc/) {
$r->custom_response
What if the request has no Content-Length: header at all? Do you let
it through then, no matter how big the body is?

Yuck. I would move the logic into whatever handles the API calls
rather than duplicating the mapping from URI's to code in two places.
That's just asking for things to get out of synch.
