Useful "X headers"
POSTED BY JONARNE 3 YEARS 40 WEEKS AGO
My hobby for a while has been to collect "X-headers". X-headers are fields in the request HTTP header beginning with an X. Put simply. These fields are kind of non-standard or proprietary add-ons to the regular fields in the HTTP header. These can be used for all kinds of fun stuff when building mobile portals. I have made a collection of some x-headers here.
Usually it is smart to blog about stuff you know. I will be the first to admit that I am on thin ice here, but I hope someone out there becomes a tiny bit more enlightened by this post.
X-headers can be used for many different things: User identification, device recognition, probing for network characteristics and much more. This information is useful both in terms of creating a good mobile experience and in terms of statistics.
I have listed a selection of headers below from devices that have visited my site. I don't know what all of these mean; many can be "man made" for all I know, but it's still interesting. If I am wrong about some, or you have additional information, please comment.
These are headers we already know very well.
