Apache traffic server reverse proxy port

Question

I am using Apache Traffic Server as a reverse proxy. Is it mandatory to use port no. 80 as the server port or any unused port (in the unreserved category) can be used?

Using port number 80 gives me a permission denied error, and using a random unused unreserved port seems to have solved the problem, but it is important to use just port no. 80?

Answer 1

You can use any port you wish. As a standard, port 80 is used for websites.

So when you type www.google.com in your browser it's the same as www.google.com:80 That's the only thing you should keep in mind.

Here's a list of the most commonly used ports. http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
