Hello all!

help me please...
On the server, Nginx used GZIP, for a savings of traffic

[code]
gzip on;
gzip_comp_level 3;
gzip_disable "MSIE [1-6]\.";
gzip_types text/plain text/xml application/xml application/x-javascript text/javascript text/css application/json application/xml+rss;
gzip_http_version 1.0;
[/code]

Need to know how works effectively GZIP.

I usually use http://www.whatsmyip.org/http_compression/
Which shows:

[code]
Original Size: 70 KB
Gzipped Size: 23.5 KB
Data Savings: 66.43%
[/code]

The problem is that my site works in a corporate network without going to internet...
How could all still see this type of information: Original Size, Gzipped Size

Thanks!
