Application error with unsupported format requests

Today I got a bunch of error messages with a user probing the login page for api information using urls like /account/login.wsdl /account/login.aspx

To me this should be a 404 rather than an application error. However the route matches the standard rails routing line map.connect ':controller/:action.:format' and then fails in the action with a Missing Template error as I don't have, and never will, a template login.wsdl.erb

I tried explicitly setting the template in the action with render :template => "login.html.erb" and return but still get the Missing Template login.wsdl.erb error.

I tried throwing this at a few high profile rails sites like 37signals or twitter and they don't crash. How can you close this hole?

Cheers, Sam

Sam--

Are you using rescue_action_in_public in your ApplicationController? You can override Rails' default to render a login page, return a 404, or whatever you prefer.
