Code style

• Use UTF-8. It’s 21 century, 8bit encodings dead now.
• Use 2 space indent, not tabs
• Use Unix-style line endings
• Keep lines not longer than 80 chars

#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault

##Steps

# select "user_status", "friends_status", "user_checkins" when authenticating
oauth_access_token = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
graph = Koala::Facebook::API.new(oauth_access_token)

# The initial was for Varnish 2.1, this has been updated for Varnish 3.
# The upgrade changes were based on the docs here:
# https://www.varnish-cache.org/docs/3.0/installation/upgrade.html
# https://www.varnish-cache.org/docs/2.1/tutorial/vcl.html
# https://www.varnish-cache.org/trac/wiki/VCLExamples

# Summary
# 1. Varnish will poll the backend at /health_check to make sure it is
#    healthy. If the backend goes down, varnish will server stale content
#    from the cache for up to 1 hour.
