Im just confused how to build this URL (easy question for you guys, I think)

[quote author="pickupman" date="1343396461"]Don't you think it would be tough for some to guess that the URI might be different an remove a segment to access the page from the real URI. You know it's an option, but no one else would. It's also unlikely that anyone not in web development even pays attention to a url, let alone manipulate it.

With that being said, just make it a private method to make it inaccessible directly.

Thanks for reply.
But I have another question about URL. Sorry if my issues was all about URL

When i typed my url for example and add another segment at the end of it which do not exist in my content, it should show an error 404 page. But instead it shows the page for the last valid segment in the URL.How could I fix that??.
