Add a frontal apache for proxying requests

Hello,
Is it possible to add another apache to do proxy. For example my kaltura is on http://kaltura.example.fr and I want to add a proxy to serve url from outside network like http://www.example.org/streaming

I tried many solutions but it fails.
This example is working but then all the links in the page are not working because they do not contains /streaming/

ServerName www.example.fr

RewriteRule        ^/streaming/(.*)$  http://streaming.example.fr/$1 [P,L]
ProxyPassMatch ^/streaming/.*$ !
ProxyPass /streaming/ http://streaming.example.fr/
        <Proxy "*">
            Require all granted
        </Proxy>
<Location "/streaming/">
    ProxyPassReverse "http://streaming.example.fr/"
    ProxyPreserveHost off
</Location>

With ProxyPreserveHost on (that I am use to have on others proxy), kaltura is not working.
