PHP/Apache Conf Prob (HTTP ERROR 406)

[Anon]

I've got DefaultType set to "text/html" in my httpd.conf file.

If I try to submit URLs of the type

http://www.site.com/code/en/156/

to certain search engines, for ex. Altavista, I get an HTTP 406 error.

http://www.site.com/code?param1=en&param2=156

works fine. At least, it does not raise an error.

I'm desperate for a fix. Please help.

P.S. I've tried setting ForceType to application/x-httpd-php.

Also:

AddType application/x-httpd-php .php

and

AddType application/x-httpd-php .php3

are also set in the conf file.
