Hmm.. document.write() seems to work just fine on Opera Mini, even when
loaded from external scripts/inlined/etc. The only problem seems to be
about timing, ie. if a page takes too long to load, the scripts will be
left behind.
I haven't had a chance to checkout your code and run it locally, but could
you confirm that Opera Mini actually gets the document.write()?
When visiting this directly, on various user-agents, I don't see a
document.write
www.mediawiki.org/w/index.php?title=Special:ZeroRatedMobileAccess&zcmd=js-banner
(I obviously get just this: window.mw.zeroConfig={"enabled":false,"id":null};
)
I'm waiting for a colleague to test and report from a network where
Wikipedia is actually free.
For your second question: Since the webpage/session/cookies are all sitting
on the server, all AJAX/inline requests will originate from the Mini Server
and not the client. The IP address will belong to our servers, and the
x-forwarded-for will be set as the client's ip.
Best regards,
Gautam
