 Rails implements the [Server Timing](https://www.w3.org/TR/server-timing/) standard to make timing information available in the web browser. To enable, edit your environment configuration (usually `development.rb` as this is most-used in development) to include the following:
 
 ```ruby
-  config.server_timing = true
+config.server_timing = true
 ```
 
 Once configured (including restarting your server), you can go to the Developer Tools pane of your browser, then select Network and reload your page. You can then select any request to your Rails server, and will see server timings in the timings tab. For an example of doing this, see the [Firefox Documentation](https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/request_details/index.html#server-timing).

 Ruby uses a slightly different approach than many other languages to match the end and the beginning of a string. That is why even many Ruby and Rails books get this wrong. So how is this a security threat? Say you wanted to loosely validate a URL field and you used a simple regular expression like this:
 
 ```ruby
-  /^https?:\/\/[^\n]+$/i
+/^https?:\/\/[^\n]+$/i
 ```
 
 This may work fine in some languages. However, _in Ruby `^` and `$` match the **line** beginning and line end_. And thus a URL like this passes the filter without problems:

 To fix the regular expression, `\A` and `\z` should be used instead of `^` and `$`, like so:
 
 ```ruby

 Since this is a frequent mistake, the format validator (validates_format_of) now raises an exception if the provided regular expression starts with ^ or ends with $. If you do need to use ^ and $ instead of \A and \z (which is rare), you can set the :multiline option to true, like so:
 
 ```ruby
-  # content should include a line "Meanwhile" anywhere in the string
-  validates :content, format: { with: /^Meanwhile$/, multiline: true }
+# content should include a line "Meanwhile" anywhere in the string
+validates :content, format: { with: /^Meanwhile$/, multiline: true }

 Note that this only protects you against the most common mistake when using the format validator - you always need to keep in mind that ^ and $ match the **line** beginning and line end in Ruby, and not the beginning and end of a string.

 * Rails 4.0 introduces `ActiveSupport::KeyGenerator` and uses this as a base from which to generate and verify signed cookies (among other things). Existing signed cookies generated with Rails 3.x will be transparently upgraded if you leave your existing `secret_token` in place and add the new `secret_key_base`.
 
     ```ruby
-      # config/initializers/secret_token.rb

     Please note that you should wait to set `secret_key_base` until you have 100% of your userbase on Rails 4.x and are reasonably sure you will not need to rollback to Rails 3.x. This is because cookies signed based on the new `secret_key_base` in Rails 4.x are not backwards compatible with Rails 3.x. You are free to leave your existing `secret_token` in place, not set the new `secret_key_base`, and ignore the deprecation warnings until you are reasonably sure that your upgrade is otherwise complete.
