get csrf_meta_tag back to the generated layout in deference to existing printed material, chomp also the generated HTML to be faithful to the output before the refactor

revises implementation and documentation of csrf_meta_tags, and aliases csrf_meta_tag to it for backwards compatibilty

code gardening: we have assert_(nil|blank|present), more concise, with better default failure messages - let's use them

Cleanup route reloading in tests. Prefer with_routing over using ActionController::Routing::Routes directly

[#1617 state:resolved]

This deprecates the use of :secret and :digest which were only needed when we were hashing session ids.

Signed-off-by: NMichael Koziarski <michael@koziarski.com>

The session is used by the form_authenticity_token method before it is
tested to be valid.  This patch moves a few lines around so that the
session is validated first.

Without this patch, if you try to use forgery protection with sessions
turned off, you get this exception message:

  undefined method `session_id' for {}:Hash

The patch includes a test that can be used to see this behavior before
the request_forgery_protection.rb file is patched to fix it.

Change the request forgery protection to go by Content-Type instead of request.format so that you can't bypass it by POSTing to "#{request.uri}.xml" [#73 state:resolved]

Don't append the forgery token to an ajax request if it's serializing a form, prevents duplicate tokens. Closes #10684 [macournoyer]
