Nginx bowser dectection not working for IE10 + 11

Question

Hi I am using nginx http browser module to checking browser version. Where I work now I have to do that on nginx rather then on the browser using JS. Anyways I need to allow only IE10 and 11 the rest of the IE's should be rewritten to a basic page. However my configuration below is blocking all IE's (all other browsers is behaving ok). Any idea why that is?

server {
listen 0.0.0.0:9000;
server_name localhost;
root /Users/charlie/Development/customerClient/dist/;
index index.html;

A bit late a reply but you are misusing modern_browser.

Define it once per layout engine with the version number of the oldest allowed.

So if you want MSIE 10.0 and above, then you need one line only for MSIE:

modern_browser msie 10.0;
