Using the URL Rewriting module could be the way to go. Try using configuration similar to the following:

This will redirect without showing an error page. If you want to show an error page then you'll need to redirect to a page that takes the return URL and does a client-side redirect to the right place.

As @inspile says you're going to have trouble doing it for sub-pages of the site. You may be able to do it using the referer to make sure it's from a link on the main site. Again the URL Rewrite module is the way to go here.
