Failed to create error_path on failsafe_response_body

Hi, Pratik.

I don't know how to write a test-case for Dispatcher, but I could confirm a failing case by following procedures below.

1) Set using MemCacheStore as SessionStorage.

2) Start rails application by 'script/server -p3000'

3) Run a following rspec examples:

describe "ActionController::Dispatcher" do

it "should render a text in '/public/500.html' when specified invalid session_id" do

`curl "http://localhost:3000/?_sess='"`.include?("We're sorry, but something went wrong (500)").should be_true

end

end

Before patched, Dispatcher could NOT get '500.html' as error_path, got '500 .html', so it failed test case.

Thanks.

We've encountered this problem ourselves. After a little research, a ticket relating to this problem was found on the old bug tracker. See

http://dev.rubyonrails.org/ticke...

Basically, its looking for '500 .html' rather than '500.html'. Changing [0..3] to [0...3] has fixed the problem.

not reproducible

Patch does not apply and looking at the dispatcher tests, there already seems to be a test for this behaviour:
