A presentation at PHP.FRL in in Heerenveen, Netherlands by Niels Leenheer
This is talk about browser sniffing. And yes, I do realise it is 2016. I know browser sniffing is ugly and we should all be using feature detection. But a quick search on Github still shows millions of lines of code referring to user agents strings. So this message clearly hasn’t landed yet. But why is browser sniffing a bad choice? This talk will dive into history and show the origin of the user agent string and the hidden battle between browser makers and web developers. It will show its simple beginnings and the horrible monstrosity it has become.
