Apache 1.3 content negotiation

Hi!

I am testing content negotiation on my server and I
have made some test pages. But I got a problem.

I have made three files: test.html.en, test.html.fr,
test.html.it and I am trying to access test.html URL.

The problem is that with the same browser configuration
(Mozilla, "en" is set as preffered language) server
sends sometimes English version (as it should) but
sometimes it sends 406 error with links to all three
files (including English). I understand the 406 error
and that it is normal that it sends it when it cannot
match a language to a file.

That is really strange as I do not change anything
between requests.

It is not proxy problem (I do not use it) or cache problem
as I sniffed my connection and to exactly the same GET
request from my browser server sends once html file and
once 406 error.

I have not found any pattern. It seems random.

And ideas?

Have you found my page
http://ppewww.ph.gla.ac.uk/~flavell/www/lang-neg.html
on this general topic?

I don't know the precise answer to your problem; but I think
if you follow the suggestions on this page, then you will be able
to get the results you wanted (even if you still don't understand
what was going wrong before ;-)

(Are you using MultiViews, or a type-map?)

Yes. I have read it. And I have also read Apache documentation
on the topic.

MultiViews.

I have discovered that after fresh restart (of Apache) everything
is working OK. But after some time, minute or two, (I do not why)
this two requests have different responses (first English (because
of LanguagePriority) and second 406):

GET / HTTP/1.1
Host: my.host.com
Accept: */*
Keep-Alive: 300
Connection: keep-alive

GET / HTTP/1.1
Host: my.host.com
Accept: */*;q=0.1
Keep-Alive: 300
Connection: keep-alive

Boggle. I don't have an explanation (at least, not yet, nor have I
any confidence that I'll be able to give one), but can you, at least,
say what the "Vary:" response header contained in each case?

Of coure. For working one:

Vary: negotiate,accept-language
TCN: choice

For other one:

Vary: negotiate,accept-language
TCN: list

If you need any logs or anything (debug mode?) ...
