Support for HTTP OPTIONS method and Microsoft Office Protocol Discovery

I ran across an interesting issue with Microsoft Office Protocol Discovery. It was generating exception emails due to its use of the OPTIONS method. See for more information.

I implemented the solution there but soon found that every request for a non-existent URI (http://localhost/asdf/asdf/as/dfff/ff), generated an exception due to with more information found out:

It is strange to me that the route matching would throw an error because the path matched but the method doesn't. Shouldn't the route matching continue through the rest of the routes before making that determination?

I have had the same issue. It would be great if rails could automatically add routes for the OPTIONS http verb based on the config/routes.rb file.

I filed an issue on Github before discovering this list : [feature request] automatically generate options routes · Issue #27655 · rails/rails · GitHub
