I have fixed the problem using virtual host and mod_proxy apache
Install mod_proxy mod_proxyhttp
Create a virtual host reached by 'http://bibli.<domain>
edit the site
<VirtualHost *:80>
ServerAdmin webmaster@localhost
ServerName bibli.<domain>
ProxyPass /
http://192.168.1.xxx:8080/
ProxyPassReverse /
http://192.168.1.xxx:8080/
ProxyPreserveHost On
</VirtualHost>
