# 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.
# 2. Varnish will pass X-Forwarded-For headers through to the backend
# 3. Varnish will remove cookies from urls that match static content file
#    extensions (jpg, gif, ...)

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

PID=$APP_ROOT/tmp/pids/unicorn.pid
