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. .SH "SEE ALSO" .IX Header "SEE ALSO" Net::HTTP
