Google says I have a 404.
the browser display a duplicate instead of 404.
Uh, which is it? I don't understand...
Oh, or are they separate 'things'? Google said you have a 404 and then you did more investigation and found another issue?
Yes, not serving a 404 for any request that's not properly formatted to generate a unique page can be an issue, even for non-php sites ... Try the same thing on almost any site: http://www.example.com/sompage.html?some=stuff-here
Most of the time you will not generate a 404, but rather a 200 OK duplicate of the page ... Solving the issue is a bit involved, and I don't have time to post on that right now, but it can be done ... I'll try to check back in later.
