If you get following error, when you try to start nginx…

[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)

For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers
