It is, SqLite 3 format.

My cache.db had grown to ~86 Mb in a couple of days of sporadic iPlayer
use. Most of the cached data blobs were, as I said yesterday, a little
under 256k and mostly binary (and clearly not compressed - lot's of
redundancy). Right at the end was some text:

I note the word "expires" close to a date a month from now. This might
explain (if this is being processed and overriding the 1 hour default
that was mentioned) why the entries are not being removed. The number
before the phrase "content-length" is probably pretty accurate for the
size of the non-text part of the cached value.
I don't know where this is from; perhaps someone else can tell, but can
it really be the result of multiple URL requests you have identified, as
it's ~250K of binary data? Perhaps these entries (over 200 of them) were
in my cache for some other reason.
