Hi,  
I’m using nginx as proxy (only) and Apache as backend.  
{Internet} -A- [nginx] -B- [Apache]  
Is the traffic between Internet and nginx (A) should be the same as  
between nginx and Apache (B)?  
When I count the traffic with FreeBSD’s ipfw I’ve got strange results.

No, it shouldn’t, at least if gzip is enabled in nginx. Internet  
traffic expected to be lower (since traffic from nginx to clients  
is gzipped if possible, while traffic from apache to nginx isn’t).

Additionally, client aborts also lowers internet traffic.
