There's been some confusion in this thread between headers used by mediawiki in determining content generation or for cache variance, and those intended only for logging. The zero carrier header is used by the zero extension to return specific content banners and set different default behaviors (i.e. hide all images) as negotiated with individual mobile carriers. A reader familiar with this might note that their are separate X-CS and X-Carrier headers but X-Carrier is supposed to go away now. Agreed that there should be a single header for content that's strictly for analytics purposes. All changes to the udplog format in the last year or so could likely be reverted except for the delimiter change, with a multipurpose analytics key/value field added for all else. > I think the question of using a URL param vs a request header should > mainly take into account whether the response varies on the value of the > parameter.

I might not have grokked the original RFC email well, but I don't understand why this was being discussed as a logging challenge or necessitating a request header. A mobile api request to just get section 3 of the article on otters should already utilize a query param denoting that section 3 is being fetched, and is already clearly not a "primary" request. Whether or not it makes sense for mobile to move in the direction of splitting up article views into many api requests is something I'd love to see backed up by data. I'm skeptical for multiple reasons. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
