Is a subdomain home page URL with a trailing slash equivalent to without?

Question

For pesky trailing slashes at the end of URLs, example.com and example.com/ are equivalent. What about subdomain homepages such as support.example.com and support.example.com/? Is it the same rule?

Answer 1

Yes.

The domain name part is processed seperately the "path" part of the URL. Subdomains are treated the same way as their parents by the web server (in fact example.com is a subdomain of com).

This is maybe easier to demonstrate in cctlds - example.co.nz behaves the same way as example.com - even though its a subdomain. ( www.example.com and www.example.co.nz have the same behaviour as well)
