Enforcing won't preserve HTTP methods

[hammady]

I have a sign_out link that has a DELETE HTTP method (browser posted it as POST with _method=delete in the query string). Because its url matches the SslEnforcer, so its protocol gets modified to https. However, the browser displays 404 and my server logs say:
ActionController::RoutingError (No route matches [GET] "/users/sign_out")
It means that it is rerouted but the method was changed to GET instead of POST, and rails didn't find this route.

I can see it normal as the browser follows the redirect using GET. May be I have to directly send sign out requests using https.
