# ./config/initializers/rewrite_ie_header.rb
# Don't forget to include the middleware file! If you have a ./lib/middleware folder in rails
# a `require './lib/middleware/rewrite_ie_header.rb'` should do the trick
#
# IE has a really stupid accept header, so here we scope its domain of mime-types that it can negotiate, otherwise we'll
# end up with weird bugs where if you hit /mcp/:id, IE will download a .ppt file instead of the .html content.
# 
# Issue documented in more detail at https://github.com/rails/rails/issues/9940.

Update

If you're looking at this in 2016, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

#If you're on Ubuntu or working with a Linux VM...

Step 1: Install the Ubuntu dependencies needed:

SSH into your server as a root or do sudo -i.

Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

Started GET "/" for 127.0.0.1 at Mon Sep 06 01:07:11 -0400 2010
  Processing by HomeController#index as HTML
  User Load (0.2ms)  SELECT `users`.* FROM `users` WHERE (`users`.`id` = 3) LIMIT 1
  CACHE (0.0ms)  SELECT `users`.* FROM `users` WHERE (`users`.`id` = 3) LIMIT 1
