X-Forwarded-Forand 2 layers of Varnish

[Jean-Christophe Petit]

Hello,

we use 2 layers of Varnish and it proved to be highly scalable and 
efficient.
But on the second layer, we are not able to get the X-Forwarded-For from 
the first layer to sent it to the Backend (Apache)
In fact, on the second layer we have 2 X-Forwarded-For (Visitor + first 
Varnish layer)
Is there something we can do on the first Varnish layer to only transmit 
the X-Forwarded-For of the visitor ?

Thanks,
