I have apache server on ubuntu 12.04 with virtual hosts and router forwarded 80 port to one of them. The directory is configured http-authentication. I need to provide authentication for the requests only when a request comes in the "outside", that is, only when the request comes through the external ip, and if I call from inside the network (or from the server at localhost), no authentication is required.
Thanks in advance for your help. Sorry for bad english.
