Why don't we continue to use the bits cache for all things resourceloader.
Can you provide a different path for these requests, such as instead of:
..
Then we can if (req.url ~ "^/m/") { tag_carrier + strip the /m/ }, so the
overhead only effects mobile requests.
Faidon has raised that it's still advantageous to shard page resources
across more than one domain for browser pipelining.

This approach will require either:
1) Adding device detection to bits for device variance
2) Using mobile varnish to handle load.php requests for resources requested
from .m domains
From conversations with Max and some folks from ops, it sounds like #2 is
the preferred approach, but I am a little nervous about it since mobile
varnish caches will have to handle a significant increase in requests. It
looks like a typical article load results in 6 load.php requests. Also,
we'll need to duplicate some configuration from the bits VCL. Ops, is this
OK given current architecture?

Non-js-supporting devices need very different
handling, as all HTML has
to
be pre-built for them on the server.
ResourceLoader has a small stub module called startup. It checks
browser compatibility and then loads jQuery and various MediaWiki
modules (including ResourceLoader core). We just need to imporove the
checks, as the my original message states:

gracefully, still no need to force them to download tens of
kilobytes needlessly)[3]
