In the answer to your new() question I briefly explained that each class needs to have a constructor method. The name of the constructor is usually similar to the name of the class that contains it. I don't know whether your manual says that the Apache class is called "Apache" or "request", but it seems that its constructor is called request(). My guess is that the phrase should say "In the case of the Apache request class, the constructor is named request()". This would be consistent with the rest of the text.
