Hi,
I’m experiencing a strange issue whereby Haproxy completely hangs when it
receives a certain request, i have confirmed that the request is received
through the following tcpdump, but it does not appear in the haproxy logs,
neither is it forwarded.

Of interest to note is the newline at the end of the body, that’s what makes
the content-length add up to 1049, is there any reason why this request is
being dropped.?
