`class Handler`

A middleware which catches exceptions and performs an internal redirect.

Definitions

`def initialize(app, location = '/errors/exception')`

Implementation

def initialize(app, location = '/errors/exception')
	@app = app
	
	@location = location
end

`def fatal_error(env, exception)`

Generate a very simple fatal error response. This function should be unlikely to fail. Additionally, it generates a lowest common denominator response which should be suitable as a response to any kind of request. Ideally, this response is also not good or useful for any kind of higher level browser or API client, as this is not a normal error path but one that represents broken behaviour.

Implementation

def fatal_error(env, exception)
	body = StringIO.new
	
	write_exception_to_stream(body, env, exception)
	body.rewind
	
	return [500, {HTTP::CONTENT_TYPE => "text/plain"}, body]
end
