How do I set up my ht access for redirects?

you probably don't want the trailing slash at the end of those unless you actually have a directory called main.html

Other than that, make sure that any images loaded on main.html either have a base href, or, are linked with the full path, i.e.

<img src="/path/to/image.jpg">

Otherwise when someone goes to

http://yourdomain.com/asdf/asdf/asdf

they'll get broken images.
