title: Mobile browsers aren't tracked by Ruby CGI script
body: <p>I placed an image link on my blog, which in fact refers to a Ruby CGI script on my Apache webserver. The CGI script provides the image data for the browsers by simply writing its content to the STDOUT, and then logs the visitors data, taken from the appropriate environment variables, tries to identify the country information through ipinfo.io, etc. Everything is going fine, however mobile browsers aren't tracked.
