After hours of googling “URL redirection with Apache”, I found lots of resources but it is hard to understand and too much complicated information. To make people clearly understand, this presentation provides clear explanation on the difficult things and good examples. It will give you a basic knowledge that you should know before digging deep into the details such as “http status code” and “rewrite rule”. There are a few examples to guide you how to do. I really hope it will be useful not only for the beginners, but also for the more advanced developers. Please let me know if you have any comments or suggestions.
