It'd be the very first API called when a request has come in, immediately after
the request and headers have been read. BrowserMatch would use it to set env
vars according to browser, which would then be used by other modules/the core
to influence their behaviour.

The order of things at the moment is:

location/file/dir walk
access check
find types

I'd suggest it should go like this:

location/file/dir walk
header parse
access check
find types

mod_browser would hook header parse instead of fixups. Note that it should go
after the loc/file/dir walk so it can work with per-dir directives.

I agree we should be closing up Apache, but we have a problem. Some clients
can't handle 1.1 responses. There is not currently a clean way to fix this. We
can either say "Pah! Any client that can't handle 1.1 is broken" or we can
fix it.

Since the 1.0 spec is totally unclear on this point, I don't see that we are
justified in saying that 1.0 clients are broken if they refuse 1.1 responses.
In which case, Apache must be broken. OK, the refusal of 1.1 responses should
be deprecated, but does that mean we can just ignore the problem?

Actually, the 1.1 spec is pretty unclear, too, as we see from the WG.
