OPTIONS requests

When I published the Costs to Expect API I was initially bemused, none of my OPTIONS requests worked, they all return “405 method not allowed”.

After searching, I diagnosed the problem. The HTTP OPTIONS request fails because the default PHP-CGI handler does not handle the “OPTIONS” verb.

The fix is simple, update or add the handler in web.config.

<remove name=”PHP72_via_FastCGI” />
<add name=”PHP72_via_FastCGI” path=”*.php” verb=”GET,PUT,POST,DELETE,HEAD,OPTIONS” modules=”FastCgiModule” scriptProcessor=”PATH\To\File\php-cgi.exe” resourceType=”Either” requireAccess=”Script” />
