Hi everybody,

I have a problem configuring haproxy as a reverse proxy for Bluemind.
When I enter the URL on a browser, it changes to the same address followed by a lot of \ and I get the message “The page isn’t redirecting properly”

In the logs of the proxy server, i get :

Nov 13 14:45:25 rproxy haproxy[5244]: 10.5.0.176:35822 [13/Nov/2018:14:45:25.581] https-in~ bk_bluemind/bluemind 0/0/0/1/1 301 381 - - ---- 1/1/0/1/0 0/0 "GET / HTTP/1.1"

In the logs of the bluemind server, i get :

Here is (part of) my configuration :

frontend https-in
	mode http
	bind *:80
	bind *:443 ssl crt-list /etc/haproxy/crt-list.txt
	acl acl_bluemind hdr(host) bluemind.mydomain.fr
	use_backend bk_bluemind if acl_bluemind
	default_backend bk_wanda
backend bk_bluemind
	mode http
	option httpchk
	http-request set-header X-Forwarded-Proto http if ! { ssl_fc }
	http-request set-header X-Forwarded-Proto https if { ssl_fc }
	server bluemind 10.5.0.48:80

Does anyone experienced such a problem or have a solution ?
