OmniAuth Google OpenID WEBrick::HTTPStatus::RequestURITooLarge

Question

I am using OmniAuth to allow users to log in with their Google OpenID accounts. When I try to log in in development mode with WEBrick, I get a WEBrick::HTTPStatus::RequestUR

Answer 1

As mentioned in railscast 236 for OmniAuth, WEBrick has trouble with long urls given by OpenID. The solution given that worked for me was to add Mongrel to your gemfile.

gem 'mongrel', '1.2.0.pre2'
