Title : haproxy: intercept all cookies and set secure attribute

This snippet shows you how to use haproxy to set the secure attribute on
cookies. You might have a backend application which is not able to set the
secure attribute on cookies or for which haproxy does the ssl offloading. This
simple frontend rspirep sets the secure attribute for all cookies.

Add the following to a `frontend` block:

rspirep ^(set-cookie:.*) \1;\ Secure

Like so:

frontend example-frontend
reqadd X-Forwarded-Proto:\ https
rspadd Strict-Transport-Security:\ max-age=31536000;\ includeSubDomains
option forwardfor except 127.0.0.1
maxconn 2000
rspirep ^(set-cookie:.*) \1;\ Secure
bind 10.20.30.40:443 ssl crt /etc/haproxy/pem/example.pem ciphers ECDHE+RSA+AES256+GCM+SHA384:ECDHE+RSA+AES128+GCM+SHA256:DHE+RSA+AES256+GCM+SHA384:DHE+RSA+AES128+GCM+SHA256:ECDHE+RSA+AES256+SHA384:ECDHE+RSA+AES128+SHA256:ECDHE+RSA+AES256+SHA:ECDHE+RSA+AES128+SHA:DHE+RSA+AES256+SHA256:DHE+RSA+AES128+SHA256:DHE+RSA+AES256+SHA:DHE+RSA+AES128+SHA:ECDHE+RSA+DES+CBC3+SHA:EDH+RSA+DES+CBC3+SHA:AES256+GCM+SHA384:AES128+GCM+SHA256:AES256+SHA256:AES128+SHA256:AES256+SHA:AES128+SHA:DES+CBC3+SHA:HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4
default_backend example-backend

This will set (and re-set) all your cookies with the secure attribute on.
