Looking through the logs on $work's site I notice that I am getting a
significant number of requests for HTML pages with gzip turned off.
The extent of this is that while these are only about 1/4 of requests the
total bandwidth used is greater than the "compressed" versions. eg:
Bandwidth Hits/minute Page size URL
438.2 Kb/s 21 h/min 154 KB http://www..co.nz/
211.3 Kb/s 54 h/min 28 KB http://www..co.nz/
Looking though the logs  and going off the knowledge that since every
browser including IE6 supports compression I am guessing that the problem
is people's proxy servers stripping off the "Accept-Encoding: gzip"
headers that the browsers are generating.
So those of you who are running proxy servers please have a quick check
and make sure it is handling compression correctly. A simple option change
may save you half your bandwidth.
Here is a test page that will indicate if compression requests are being
sent through to remote sites.
 and ignoring the people like smokeping.net24.net.nz who like using me
as a test site.
