hi all, regarding the get_meta_tags function in php,

1. Can you get meta-tags from "http://blahblah.com" instead of from pages in your own site?

2. Can you just put "http://www.blahblah.com" or do you have to specify the entire path "http://www.blahblah.com/blah.html"

3. Does the "/" at the end of a path affect it?

I've checked the php.net manual but it doesnt say, so thank you for your help...
