As long as your robots.txt is accessible by search engines on your server, any user can directly access it by typing its address.

You could block its access via .htaccess using specific user-agent filters, though, namely authorizing only search engines user agents to access it.

As long as no one is fooling around with a fake user agent to blind guess your robots.txt file, you should be safe.

The real question is: why don't you want your users to see it?

If any informaton is too important to be visible on the web, it should not be published online (unless behind a password-protected wall).

Can search engine robots read file with permission 640?
i tried searching for this on google but i came up empty. i want to know how to lock object 2 5 inches away from the corner of object 1? i want it to stay 5 inches away even if i re-scale.

can someone please help me? how do i lock cube 2 5 inches away from the edge of objects 1?

here is an image of what i want to do:



EDIT:
i want to offset "cube 2" 5 inches away from the bottom right vertex of "cube 1" no matter where "cube 1" is?

so if i move or scale "cube 1", "cube 2" would still be offset 5 inches from the bottom right vertex of "cube 1"
