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, */* Accept-Language en-US User-Agent Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding gzip, deflate Host www.site.jp Connection Keep-Alive Cookie __utma=251775897.296901576.1350358193.1350409315.1350435377.4; __utmz=251775897.1350358193.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none) ============= Header response: Key Value Response HTTP/1.1 200 OK Server nginx Date Wed, 17 Oct 2012 19:22:23 GMT Content-Type text/javascript Last-Modified Wed, 22 Aug 2012 07:53:49 GMT Transfer-Encoding chunked Connection keep-alive Cache-Control max-age=290304000, public X-Powered-By PleskLin ============= /etc/nginx/conf.d/gzip.conf: gzip on; gzip_proxied any; gzip_types text/plain text/xml text/css application/json application/javascript application/x-javascript text/javascript application/xml application/rss+xml application/atom+xml application/rdf+xml; gzip_vary on; gzip_disable ""MSIE [1-6]\.(?!.*SV1)""; ============= If Im missing any other info please let me know." defect closed major nginx-core 1.3.x invalid gzip, deflate bug Linux v3413.vir.kagoya.net 2.6.32-042stab055.16 #1 SMP Fri Jun 8 19:22:28 MSD 2012 x86_64 x86_64 x86_64 GNU/Linux "nginx version: nginx/1.3.0 built by gcc 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) TLS SNI support enabled configure arguments: --prefix=/usr/share --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --lock-path=/var/lock/nginx.lock --pid-path=/var/run/nginx.pid --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --user=nginx --group=nginx --with-ipv6 --with-file-aio --with-http_ssl_module --with-http_realip_module --with-http_sub_module --with-http_dav_module --with-http_gzip_static_module --with-http_stub_status_module --add-module=/root/nginx-1.3.0/agentzh-headers-more-nginx-module-6586984/"
