I have a website in a server, pointing to a domain, say example.com I want to create a new webserver (running in another port) for a second website. This is no problem.
The thing is that I need the second website to be reached in a url like example.com/second_website, So that I create the illusion that it is part of the first website.
The server is in windows. If I can get a general idea of what to look for, I would search for the details myself. The reason why I am not just expanding the first website by simply adding the code of the new website in it is that we need to use other technologies for the new website.
