rendering the template.
It is initialized with a block that, when called, starts
A valid Rack::Body (i.e. it responds to each).
:nodoc:
* Rack::Cache needs to support streaming bodies
* Support streaming from child templates, partials and so on.

def log_error(exception)

This is the same logging logic as in ShowExceptions middleware. 
def log_error(exception)
  logger = ActionView::Base.logger
  return unless logger
  message = +"\n#{exception.class} (#{exception.message}):\n"
  message << exception.annotated_source_code.to_s if exception.respond_to?(:annotated_source_code)
  message << "  " << exception.backtrace.join("\n  ")
  logger.fatal("#{message}\n\n")
