Description

https://tools.ietf.org/html/rfc2616#page-34

The last paragraph of RFC 2616/4.4 stipulates that a notification (warn() in Perl, ISTM) should be given when the payload length doesn’t match the Content-Length header.

Right now there’s no such warn() happening … maybe do a recv()/MSG_PEEK to see if there is more to read on the socket, then warn() if so?

Research direction

Start by locating read_entity_body() and reviewing how it compares the payload with the Content-Length header. Read RFC 2616 section 4.4 and inspect the socket-reading behavior before deciding how a mismatch can be detected. Done means the specified warning is emitted when the payload length is inconsistent with Content-Length, without changing normal reads.
