The server normally returns a 404 response if an unknown URI is requested, but it also returns a lame empty message. This lets you do a 404 response with a custom message for special URIs.
Sets the message to return. This is constructed once for the handler so it's pretty efficient.
# File lib/mongrel/handlers.rb, line 80 def initialize(msg) @response = Const::ERROR_404_RESPONSE + msg end
Just kicks back the standard 404 response with your special message.
# File lib/mongrel/handlers.rb, line 85 def process(request, response) response.socket.write(@response) end
