Bug ID: 61063
Summary: Data loss in mobile webrequests.

So, I've been noodling around in the request logs recently and I've seen a lot
of rows that have null entries for some columns. Not too big a deal with most
of em - some are things like referrer, or user language, where I can see it not
being provided by the client.
Today, though, I encountered requests without a MIME type. Not even requests
for weird things - I'm talking, pages like the enwiki main page, or the article
on India. I've backtracked the examples I pulled out into hive itself and
confirmed that the elements are blank there, too (happy to provide em in
private to anyone investigating this).
I'm kinda confused about what's going on. It shouldn't really be possible to
send a request and return it without that data, and the invalid requests are
coming from both Android and iPhone devices. An investigation upstream (for
example, checking if they're null in the varnish memstore, too) would be most
welcome.
