no trailing slash results in 301

[Rapsey]

http://somewebaddress/test  will result in a 301 to the server for which
haproxy should be proxying requests. So the user is redirected to
http://localhost:8080/test.
http://somewebaddress/test/ works fine.
I tried backend nginx and apache and it is the same.

Anyone have an idea whats going on? My haproxy config:

global
        maxconn 10000
        pidfile /tmp/haproxy.pid

defaults
        contimeout      5000
        clitimeout      50000
        srvtimeout      50000

frontend httpfront *:80
        mode http
        option forwardfor
        acl acl_str path_end .str
        use_backend someservice if acl_str
        default_backend nginx

backend someservice
        mode http
        option httpclose
        server strserver 127.0.0.1:6002

backend nginx
        mode http
        option httpclose
        server nginxsrv 127.0.0.1:8080
