apache content negotiation and $_GET

All,

I've got a weird issue concerning $_GET and apaches content negotiation.

situation one:

files in htdocs/:

phpinfo.phtml.en (all it does is call phpinfo()).
phpinfo.html - apache type-map

if I load URL = https://server/phpinfo?klop=99, I see no _GET variables
listed. (with the URL, apache will pick the phpinfo.html file, treat
it as a type-map and load phpinfo.phtml.en)

if instead I skip the content negotation, and use URL =
https://server/phpinfo.phtml.en?klop=99, the $_GET variable is
available.

Any suggestions?


thanks,

I should have mentioned I'm using php 5.2.0 and apache 2.2.3.

This has nothing to do with PHP, and there's only a very little chance
you get a successfull result here.
Your Apache type-map probably just doesn't take the $_GET variables
with it, but don't ask me how to fix ;) I can provide a PHP solution
for it ;)

Since I don't have either of those files in my Apache/htdocs directory, I assume
it is a Linux thing. I have Apache and PHP installed in Windows, and the way I
see the PHP information is with a file named phpinfo.php. It contains a single
line:

<?PHP phpinfo(); ?>

If I call it with a query string, http://domain/path/phpinfo.php?var=data, The
_GET["var"] parameter shows up under "PHP Variables."

Yeah, that is possible - I was wondering whether to blaim PHP or Apache.
I just thought there was litte risk of apache throwing away the
querystring during content-negotiation.

I can tell that the $_SERVER[query-string] variable is not set when
using the type-map, but it when I go straight to a specific file. That
does seem to suggest apache is at fault.

Actually it suggests exactly that. Apache is giving PHP the query
string, and PHP does nothing to it before it puts it in the $_SERVER
variable. So this basically means that when you use the type-map Apache
is not populating the query string variable.

In short, I'm 5-9's% certain it's Apache that's throwing it away.

PHP pretty much just blindly passes on whatever is in the REQUEST_URI
into $_GET.

So the GET data isn't surviving the type-map forwarding.

So your question boils down to:

Why isn't Apache's type-map propagating the GET arguments?

This question has no PHP in it; You'll probably find the answer
faster/better in an Apache milieu.
