I am getting an problem with one user. Regardless of what he is doing he eventually ends up getting tossing an ActionController::InvalidAuthenticityToken error. I've attempted getting him obvious his browser's cache, snacks, etc. He will get this using both Opera and Ie. I am baffled why this is occurring just for him. Everything I actually do in each and every browser works fine.

He's running Home windows Vista Home.

Our stack:

  • Ubuntu 9.10
  • Ruby 1.8.7-248
  • Rails 2.3.9
  • Passenger 2.2.11
  • Apache 2.2.12


Would you use page, action or fragment caching? Make sure you are not caching the authenticity token.
