woo-commerce fastcgi-cache session-conflict solution (attempt)

You can jump to code directly

How it works?

1. Cache product pages

Following line does't have /products.* page. This tells Nginx to cache all product pages by default.

Idea is fast loading product pages will improve scalability of a store and also conversion.

You can throw this into lib/core_ext in your rails app to prevent implicit connections being made with a stack trace to track down the errant code.

# This is hacked from the original code for Rails 4.1. Owen went in and hacked the ConnectionPool
# so it's not fool proof but prevents ShopHotelsCommand from grabbing dozens of idle DB connections.
#
# If you create a thread yourself, if it uses ActiveRecord objects without
# explicitly checking out a connection, one will still be checked out implicitly.
# If it is never checked back in with `ActiveRecord::Base.clear_active_connections!`,
# then it will be leaked.
