You might have some sections of your Wordpress site that are only accessible for your Wordpress user. Pretty easy to protect the page or post in Wordpress for only the registered user but what about the attachments of the post/page (files, images)?

In a recent project, I had to redirect a specific category archive to a Wordpress page. I wanted to show special content when people were accessing the category archive page. This is actually pretty easy using the Wordpress wp_redirect function.
