Always sending gzip?

[Simon Lyall]

Getting a weird thing where the server is returning gzip'd content even when we don't ask for it.

Running 2.1.5 from the rpm packages

Our config has:

# If Accept-Encoding contains "gzip" then make it only include that. If not
# then remove header completely. deflate just causes problems
#
if (req.http.Accept-Encoding) {
     if (req.url ~ "\.(jpg|png|gif|gz|tgz|bz2|tbz|mp3|ogg|mp4|flv|pdf)$") {
         # No point in compressing these
         remove req.http.Accept-Encoding;
     } elsif (req.http.Accept-Encoding ~ "gzip") {
         set req.http.Accept-Encoding = "gzip";
     } else {
         # unkown algorithm
         remove req.http.Accept-Encoding;
     }
}

But:

$ curl -v -H "Accept-Encoding: fff"  -H "Host: www.xxxx.com" http://yyy/themes/0/scripts/getTime.cfm > /dev/null
