Good =)

Some comments to your text :)

That reads like as if mod_negotiation itself was disabled per default in
Apache (Stefan, if you kept on reading: I'd absolutely support this ;-)
)... is this the case, OR do we just have the effect that is does (as it
should) no longer work for the files whose php files were removed?

Again, that reads a bit, as if negotiation was generally not
"available".
Perhaps if we write: "so by default the MultiViews support for PHP files
is disabled in Debian packages."

[Optionally (but I don't insist), one could add something like the
following here:]
(unless another way than Debian's default way of enabling PHP is used)

Correct :)
And actually... if it's really HTTP Negotiation that is desired (and not
tiding URLs from /foo.php to /foo) we MUST NOT use prevent the
file.php.foo issue, because we need to allow things like:
foo.php.en (e.g. returning English content)
foo.php.de (e.g. returning German content)

I, personally, would rather turn up that like this:
"If what you actually want, is to enable tidy URLs (e.g.
http://example.org/foo can be used instead of
http://example.org/foo.php) HTTP Content Negotiation is not what should
be used anyway.
That would be better accomplished by URL rewriting (via mod_rewrite)
rules where one can explicitly specify what gets rewritten as what.

That example contradicts IMHO a bit the intention that we suppose the
user to have:
We expect that he wants to get a file "/foo.php" be accessible via
"/foo", right?
So the user most likely doesn't have files "/foo.html" or "/foo.js" in
addition (which would then of course be negotiated, too - likely with
ambiguous results). Because auf this, a URL "/foo" should not get
"rewritten", because negotiation only happens (IIRC) when the "target"
file exists.

I'll try to write you some mod_rewrite rules later; I'm just on the
train right now and I'll have to give lectures tomorrow, so not sure
when I find time.


Hope that helps,
Chris.
