CookieOverflow when using with Yahoo OpenID

[JasonBarnabe]

Getting a CookieOverflow when I try to use this with Yahoo's OpenID, which means it's storing too much (over 4KB) in the session. A session dump indicates:

OpenID::Consumer::DiscoveredServices::OpenID::Consumer::: 1144 bytes
OpenID::Consumer::last_requested_endpoint: 892 bytes
omniauth.origin: 1718 bytes

Combined with the stuff I already put in the session, this pushes it over the limit.

I'm not sure if this is fixable, since 4kb is going to remain the limit for a cookie. I may look into this a bit more, so leaving open for now.
