Re: [webkit-dev] New iOS versions sending bogus User-Agent build data
I can totally understand your intentions, it feels like that in 2018 UA should
not be a relevant piece of information, and especially not be a factor in the
decision if a server should serve a website to a certain request.
But UA is how the Internet currently works. Correct me if I'm wrong, but it
feels
like you are trying to change the Internet. Are you trying to get rid of it for
good?
I understand that these kind of drastic, revolutionary, changes might take
casualties,
I feel like the industry was not given a chance to adopt to this change.

Hi,
The very point of no longer sending the verison in the user agent is to
make it difficult for websites to determine the operating system
version.
We already have to deal with enough serious web compatibility problems
caused by the rest of the information in the user agent. I'm pleased
that the version number is now stable -- that's a huge improvement --
but I won't be happy until Safari and other major browsers start
sending fully-randomized UAs, or else a stub or blank UA
("Mozilla/5.0").
Michael

Re: [webkit-dev] New iOS versions sending bogus User-Agent build data
Actually it does, a lot! I guess that soon it won't be possible to determine iOS version distribution using User-Agent sniffing. Right? Is there an alternative for the browser to tell the iOS version?

Re: [webkit-dev] New iOS versions sending bogus User-Agent build data
Hi Konstantin, Thanks for your prompt response :-) I didn't notice this bug and the respective patches. I read the report and still find it hard to understand, if "User Agent sniffing is a terrible way to determine whether a browser supports certain features", what is the correct way of doing it?

[webkit-dev] New iOS versions sending bogus User-Agent build data
Until iOS 11.3, User-Agent build data contained the build that corresponds to the device (e.g. Mobile/15D100 if the requesting device was running iOS 11.2.6). Since iOS 11.3 was released I noticed that the User-Agent that is reported to the brower is reporting a bogus build, i.e Mobile/15E148, regardless to the iOS version that the requesting device is running. I would expect that a device that runs 11.3 will reprot a different User-Agent than a device that runs 11.3.1 and certianly than a device that runs 11.4 (Beta 1 & 2). I just wonder if my observation is an expected behavior, and if so, what is the intention behind it. If this behavior is not intended and expected, I would love to research it and propose a patch (would be my first Open Source contribution). ___ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev
