These applications will include our library with a script tag in their html code, and the applications are in different servers and domains. Testing a bit all these stuff, we get an error:

With mod_proxy, assuming you want to proxy http://example.com/remote/path

<VirtualHost *>

     # ...

     ProxyRequests Off
     # turn the next line off if you are proxying to a NameVirtualHost
     ProxyPreserveHost On

     <Proxy *>
         Order deny,allow
         Allow from all
     </Proxy>

     ProxyPass /local/path http://example.com/remote/path
     ProxyPassReverse /local/path http://example.com/remote/path
     # ...

</VirtualHost>
