* if a client sent a full request then shut its write connection down, then
the request was aborted. This case was detected only when using haproxy
both as health-check client and as a server.
* if 'option httpchk' is used in a 'health' mode server, then responses will
change from 'OK' to 'HTTP/1.0 200 OK'.
* fixed a Linux-only bug in case of HTTP server health-checks, where a single
server response followed by a close could be ignored, and the server seen
as failed.
* renamed 'haproxy.txt' to 'haproxy-fr.txt'
* large documentation and examples cleanups
* fixed multi-cookie handling in client request to allow clean deletion
in insert+indirect mode. Now, only the server cookie is deleted and not
all the header. Should now be compliant to RFC2109.
* added a "nocache" option to "cookie" to specify that we explicitly want
to add a "cache-control" header when we add a cookie.
It is also possible to add an "Expires: <old-date>" to keep compatibility
with old/broken caches.
* some doc and examples cleanups
