On the http-check expect example
(https://docs.haproxy.org/dev/configuration.html#4.2-http-check%20expect)
there is a typo
-http-check expect header name "set-cookie" value -m beg "sessid="
+http-check expect hdr name "set-cookie" value -m beg "sessid="
http-check expect status 200,201,300-310
# be sure a sessid coookie is set
- http-check expect header name "set-cookie" value -m beg "sessid="
+ http-check expect hdr name "set-cookie" value -m beg "sessid="
# consider SQL errors as errors
http-check expect ! string SQL\ Error
