thx 👍

I add something at line 39, but map section still not test ( i add that at location section so i can't use map )

I think ~* must be inside string

In case someone finds this in the future:

• the map directive needs to go into the http block
• make sure to quote the whole string, including ~* (see comment above)
• the first if statement is missing a space between the if and the parentheses (if( instead of if ()
• everything under the map directive, i.e. the if statements, need to go into a location block (likely location / {....})
• the regex neeeds to be updated from http://detectmobilebrowsers.com/

I had no idea this many people had starred this gist. I've made the suggested changes. Thanks @herrbuerger.
