What's the HTTP server software you're running this against?

I've just been tidying up my tools and found a script which checks
which HTTP methods are enabled on a given site. I ran it against my
site and it said PUT is enabled. I know that it isn't so I manually
tested it and proved it wasn't enabled. I checked what it was actually
sending and it was trying to PUT to / so I tried that and got a 200
back along with the content of my index page. I tried again with
another page and got the content of that page.

So for some reason PUT is acting as a GET for pages which exist, I
checked OPTIONS and that is doing the same both of them only work with
HTTP 1.1, not 1.0.

I've tried a few sites, apache.org, pauldotcom.com and microsoft.com
all fail but php.net gives back the content.

nc php.net 80
PUT / HTTP/1.1
Host: php.net

HTTP/1.1 200 OK

If this common it might be a nice way to bypass IDS that are looking
for GET or HEAD methods or to bypass restrictions which lock out those
two methods.

Comments?
