As a follow-up to my earlier post about having problems with the AxKit
caching mechanism, I've managed to poke through it to build up the
following _kludge_. It works (here), but there's definate "YMMV" attached
to this one.
I'm posting primarily so that someone more intimate with the innards of
AxKit can examine it a bit further and figure out why its actually doing
it this way. From tracing through the code a bit here, it seems that
AxKit actually tries to serve up the document _twice_ when its cached
(once from cache in 'run_axkit_engine', and once in 'deliver_to_browser').
Quirk here is also that we spit out _two_ sets of HTTP headers, which
probably isn't right either.
Worse yet, I'll take it from the lack of other people commenting on this,
that I'm likely the only poor sod out here who's experiencing this
problem. If so, how come? (it looks like a code-flow bug to me).
