.IX Header "DESCRIPTION"
Same interface as \f(CW\*(C`Net::HTTP\*(C'\fR but it will never try multiple reads
when the \fBread_response_headers()\fR or \fBread_entity_body()\fR methods are
invoked.  This make it possible to multiplex multiple Net::HTTP::NB
using select without risk blocking.
.PP
If \fBread_response_headers()\fR did not see enough data to complete the
headers an empty list is returned.
.PP
If \fBread_entity_body()\fR did not see new entity data in its read
the value \-1 is returned.
