setting cookie with domain

Question

This is pretty much a basic question since I got a bit confused

When we set a cookie with domain .mydomain.com refers to use the same cookie over subdomains, what if I do .test.mydomain.com does it mean urls like helloworld.test.mydomain.com will be able to re-use the cookie?

Yes, that's how it works. There's no special detection of what level the 'subdomains' are, everything is really a subdomain to the TLD at the least. What if you had a .co.uk address?
