[bioontology-support] [BioPortal] Feedback from Jan Hudecek

In regards to seeing the stack trace and configuration information, we agree that this is bad practice. There is a very peculiar failure scenario in which this can appear, and it happened this morning while you were using the site. We're taking steps to make sure the stack trace and debug information doesn't show even in this particular state.

Thanks for pointing it out!

I've accessed your API without having a key, I read that I have to register at but when I open the link it spits out a 500 error page including the stack trace and whole server configuration, starting with 

#<ActionController::Session::MemCacheStore:0x007fee62d5ec80> unable to find server during initialization. (RuntimeError)
  /srv/rails/BioPortal/shared/bundle/ruby/2.0.0/gems/actionpack-2.3.17/lib/action_controller/session/mem_cache_store.rb:20:in `initialize'

You should really get it to display just a generic server error page, this is insecure.
