body truncated on extra reads

[John ORourke]

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
