/.well-known/caldav and carddav with haproxy

Hi,
you gave the right hint, but i had to config this:

    acl caldav-endpoint path_beg /.well-known/caldav                                                   
    http-request set-path /remote.php/dav if caldav-endpoint       
    use_backend nextcloud-http if caldav-endpoint                      
                                                                                                       
    acl carddav-endpoint path_beg /.well-known/carddav      
    http-request set-path /remote.php/dav if carddav-endpoint          
    use_backend nextcloud-http if carddav-endpoint
