Open multiple pages in Mobile Safari?

Alright, this might be a really simple question, but I can't find an answer.

On the Apple site it says that some pages automatically open up in a new page, but I'm wondering how one could cause that to happen at will. For example, if I'm reading a blog and I want to open up a link but keep the blog open, how do I do that? Is it possible?

Thanks for any info!
