server.document-root        = "/home/pi/kwc"
server.port                 = 81

server.port to port 81

sudo usermod -a -G www-data pi

Installation haproxy

haproxy is necessary to use port 80.

sudo apt install haproxy

add following lines at the end of /etc/haproxy/haproxy.cfg:

frontend public
        bind :::80 v4v6
        default_backend lighttpd
        use_backend printer if { path_beg /printer/ }
#        use_backend webcam if { path_beg /webcam1/ }

        acl is_websocket path_beg /websocket
        acl is_websocket hdr(Upgrade) -i WebSocket
        acl is_websocket hdr_beg(Host) -i ws
        use_backend websocket if is_websocket

backend lighttpd
        reqrep ^([^\ :]*)\ /(.*)     \1\ /\2
        option forwardfor
        server lighttpd1 127.0.0.1:81

backend printer
        reqrep ^([^\ :]*)\ /(.*)     \1\ /\2
        option forwardfor
        server printer1 127.0.0.1:8080
