Based on many ideas that were put forth, I would like to seek comments on
this ZERO design. This HTML will be rendered for both M and ZERO subdomains
if varnish detects that request is coming from a zero partner. M and ZERO
will be identical except for the images - ZERO substitutes images with
links to File:xxx namespace through a redirector.
* All non-local links always point to a redirector. On javascript capable
devices, it will load carrier configuration and replace the link with local
confirmation dialog box or direct link. Without javascript, redirector will
either silently 301-redirect or show confirmation HTML. Links to images on
ZERO.wiki and all external links are done in similar way.
* The banner is an ESI link to */w/api.php?action=zero&banner=250-99* -
returns HTML <div> blob of the banner. (Not sure if banner ID should be
part of the URL)
Expected cache fragmentation for each wiki page:
* per subdomain (M|ZERO)
* if M - per "isZeroCarrier" (TRUE|FALSE). if ZERO - always TRUE.
3 variants is much better then one per carrier ID * 2 per subdomain.
P.S.
Redirector is a Special:Zero page, but if speed is an issue, it could be an
API calls (which seem to load much faster). The API call would redirect to
the target, or could either redirect to the special page for confirmation
rendering, or output HTML itself (no skin support, but avoids an extra
redirect). Might not be worth it as javascript will be available on most of
our target platforms now or soon.
