Never trust the user-agent header
September 12, 2008 – 1:54 pm Tags: WebSomething I just have to share: an entertaining and informative read on the history of the browser user-agent string.
I always did wonder why all browsers claim to be Mozilla when they are not… And clearly, the advice given by many JavaScript gurus to never use user-agent sniffing to determine browser capabilities is very good – just look what kind of a mess it will lead to, not to mention that if someone someday changes their UA string or comes up with a new browser, everything will break – just like the frames.

I’m proud that Opera finally decided to be sensible by default. It means they have to build in crazy userscript to detect and work around brain-dead browser sniffing, but it seems to work.
