Can I run two web servers on the same computer?

Question

I just found out that I can write a really simple web server using Python. I have already an Apache web server I would like to try the Python based web server on this machi

Answer 1

The webservers would have no say in who services a connection request (this task is still at the operating system level). Furthermore, without special socket options, the socket must be bound to a unique combination of interface, internet address and port.
