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/
