Actually I figured it out with the help from Benoit. It looks like when just specifying the URI haproxy still uses the OPTIONS method to check? For some reason it wasn't returning a 404 error if the file wasn't there, it may be the way IIS works but I don't have anything to test this with. Anyway I added the HEAD method and all is fine and working correctly now.
