Description
Hello guys,
This is my very first bug report so bear with me.
For some reason gzip compression is not working for Internet Explorer 9, it does work for FireFox and Chrome browsers but not for IE9. When inspecting the HTTP header response Im not getting any "Content-Encoding: gzip" field when trying with IE9, this field shows up just fine with the other two mentioned browsers. Some detailed info is below, do keep in mind that this is happening with any .js or .css files I have tried so far on IE9.
=============
Header request:
Key Value
Request GET /wp-content/themes/site/js/jquery.scrollTo-min.js HTTP/1.1
Accept text/html, application/xhtml+xml, */*

/etc/nginx/conf.d/gzip.conf:
gzip on;

gzip_vary on;
gzip_disable "MSIE [1-6]\.(?!.*SV1)";
=============
If Im missing any other info please let me know.
Looking into request with browser internal tools is useless in most cases. In particular, IE 9.0 fails to properly show Content-Encoding (just tested). Look at what happens on the wire with tcpdump/wireshark, or use nginx debugging (or even access_log) to see what happens instead.
