[users@httpd] Content Negotiation and PHP
I have web hosting with a company called 1&1, running Apache 1.3.
Although their content negotiation appears to be working correctly for
most files (.html, .jpg, .gif etc, and also language negotiation) I
can't work out how to get PHP pages to negotiate. I'm not getting any
help from 1&1 - they won't give advice on user programming!
As far as I can see, all I should need to do is add the following to my
.htaccess file (I obviously do not have access to the server config files):
AddType application/x-httpd-php .php
Options +MultiViews
I've worked this out from searching on the web. But I suspect this
might only be for Apache 2? I have Apache 2 at home and it works
perfectly with the AddType directive in httpd.conf.
If I call up a file with the .php extension, the page is parsed correctly.
If a call it without the extension, then I want it to find the file
*with* the extension. But all I get is a 404 Not Found.
Can anyone help?

Note that at the moment I haven't got the AddType directive in my
.htaccess as I have a test forum on the site that I wanted my users to
have a look at, and putting the AddType directive in causes all requests
to PHP files to fail (the browser tries to download the file instead of
rendering it because the MIME type is wrong). So I now think the 404
Not Found error is a red herring - it's just a symptom of my ISP not
having AddType in the main config file.

I wish more people were as thoughtful as you. However, I think having URIs
ending in .html is OK, since that is the format the client gets regardless
if it is PHP, ASP, Perl that is generating it.

No, not unless you append the [R] flag to the rewrite rule. As it was, it
should be an internal redirect.
You can also have a rule like this:
RewriteRule ^(test1|test2|test3)$ $1.php [L]
However, if you have many documents, I suggest trying my other alternative,
that automatically rewrites "all" requests that exists with the extension
added.

I'll have a play with that. Thank you for the suggestion.
Yes, it's extension hiding that I really want, not the negotiation, as
there will not be both .html and .php files of the same name. I just
want to write my site with extensionless links from the start using
.html files, then in the future rename them to .php without breaking
links or bookmarks. The only problem is if the rewrite will cause the
extension to appear in the address bar - I would want the URL to remain
as the requested URL, not the URL that was found.

In this case, it very much looks like they have a non-standard or faulty
configuration. They might not be aware of the problem, since not many use
content negotiation this way.
As a workaround you can always use mod_rewrite to internally redirect the
requests. IF you do this to avoid the file extension, and not the true
purpose, that is, negotiation.
Specifically:
RewriteEngine On
RewriteRule ^test$ test.php [L]
Or, you can try a more general approach:
RewriteEngine On
RewriteCond /your/doc/root%{REQUEST_URI}.php -f
RewriteRule (.*) $1.php

OK. I think I've established now what *should* be done, it's just a
question of finding out from 1&1 how to do it in their particular
installation. It may be that they can't support full content
negotiation - I know that Titan and Nethosted can't do it. And when I
first contacted 1&1 to ask them what I should put in my .htaccess file,
they just replied that they won't help with personal development! Oh
well, I'll continue...

If PHP handles the file, it will reset the Content-Type to text/html, so
this behaviour implies that PHP does not handle it.
The issue here might be that they use a different MIME type, eg.
application/x-httpd-php3 or something, and your AddType overrides that, thus
resulting in PHP not working.
I'm not sure why you should need to use AddType at all, isn't PHP files
already recognized?
I'm with Joshua, the server seems messed up. The giveaway is the 404, while
it still have the Content-location header set correctly.
I suggest you contact the admins so they can look into it. Only they
(hopefully) know how the main server is configured.

See:
http://httpd.apache.org/docs/misc/FAQ.html#passwdauth
for why this is a very bad idea.
If you still want to do it, there are several modules under
http://modules.apache.org/ that can do the job.

I'm using it because that's what the Apache documentation tells me to do
and what all pages I've searched for tell me to do and the advice given
so far in all forums and discussion groups!
Can you explain what to put in a SetHandler directive then? How do I
use that?
I've tried the following (found in only one web page and advised on this
mailing list that it *should* work in Apache 1.3 even though it was only
intended for Apache 2.0):
AddHandler php-script php
AddType text/html php
But the effect this has is to give me the source of the PHP, not the
result of the PHP. In other words, the file is not being passed to the
PHP parser.
Please see the following:
http://www.nantperis.org.uk/test/test - .htaccess with MultiViews & AddType
http://www.nantperis.org.uk/test2/test - .htaccess with just MultiViews
http://www.nantperis.org.uk/test3/test - .htaccess with AddHandler & AddType

That kind of AddType hack is a relic from the NCSA (pre-Apache) server.
It's a workaround for a design defect, long since fixed. It is obsoleted
by the introduction of AddHandler and not dispatching on content-type.
I'm not sure why you're trying to do this with content negotiation.
Why not just use SetHandler in a <Files>?

I have now created a new folder with its own .htaccess file consisting
of just the following:
Options +MultiViews
AddType application/x-httpd-php .php
Try calling it up the test.php file that is in the folder both with and
without the .php extension, i.e.
http://www.nantperis.org.uk/test/test.php
http://www.nantperis.org.uk/test/test
In both cases, the browser pops up a Download File dialog box because
the MIME type is not text/html.
If I was to remove the AddType command from .htaccess, it would execute
the file properly if you call it with the .php extension, but produce a
404 Not Found if you call it without the extension.

I'm not sure exactly what is going on here, but I suspect you are
using a messed up apach or php install. In particular, if you look at
the Content-Location header in the HTTP response, you'll see that it
properly points to tt.php. But for some reason, the subrequest to
deliver that file fails. I have no idea why.

Re: [users@httpd] Content Negotiation and PHP
Posted by Chris Simon <os...@zetnet.co.uk>.
It strikes me that the AddType command is indeed what I should be using
(with the .php extension) as 1&1 haven't got this in their config file -
which is perfectly OK. But the server is not returning the page as
text/html, instead as application/x-httpd-php which obviously the
browser doesn't understand and tries to dwnload it to disk instead.
So...internally Apache needs to know the source is
application/x-httpd-php so that it can send it to the PHP parser for
processing, but the resulting file needs to come to the browser as
text.html. Where is the missing link?? What tells Apache/PHP to retrn
files as HTML?
All I've got is the following command:
AddType application/x-httpd-php .php
Does this tell Apache internally that the file is PHP, or does it tell
Apache to return the page to the browser as PHP, not HTML? Or does it
do both, and can I add another command to change the MIME type of the
resulting file to HTML?

Yep, it's definitely a 404. Please try it at
http://www.nantperis.org.uk/tt - but if you call it with
http://www.nantperis.org.uk/tt.php then it works. Note that Content
Negotiation *is* working on the site because
http://www.nantperis.org.uk/contact works, which is a html file. And in
fact the main URL http://www.nantperis.org.uk/ works and it's language
negotiated as well - the filename is actually index.html.en and
index.html.cy. It's only the PHP negotiation that doesn't work.
I've read the link you gave but it only applies I think to Options
directives that are "absolute". I have a plus character before the
MultiViews parameter which makes it "relative" so that all the other
options don't get reset. My .htaccess file is simply the two lines I
gave before:
Options +MultiViews
AddLanguage en .en
AddLanguage cy .cy
I've tried adding the AddType directive but this causes both URLs (with
and without the .php extension) to produce a browser dialog asking me to
download a file of type application/x-httpd-php instead of rendering the
page.
I've tried the fix on the other link you gave:
Replace the AddType line with:
AddHandler php-script php
AddType text/html php
This causes the Content Negotiation to work and the file to be found,
but it's parsed as HTML and the PHP bits are ignored.
Does this point towards the web host's configuration being wrong?

If you are really getting 404, then the problem is that your Options
directive is not applied in the correct place in the config file.
See:
http://httpd.apache.org/docs/misc/FAQ.html#options
You may also be getting a "no acceptable variants" error, in which
case you should see:
http://tranchant.plus.com/notes/multiviews
which should work in 1.3, even though it says it only works in 2.0.
