body truncated on extra reads

Hi folks,

I'm curious - can anyone explain what actually happens internally if you
try to read more from $r->read() than specified in the Content-Length
header?

I noticed when trying subsequent calls to read after all bytes had been
read that it truncates the buffer, which I guess is understandable as it
could be the next request. I'm just wondering wether $r->read( $buffer,
1000 ) is a bad thing to do if the incoming content is only 900 bytes.

cheers
John

What used to happen is it would hang the process forever. Not sure if
it still does. Is there a reason you're not using Apache2::Request or
CGI.pm?
