I'm using drupal 7. I have a content type called News Item. On my home page, I have a block+view that lists the most recent news items. What is shown is the title of the news item, a brief description, and a read more link to the news item. When a person clicks on the read more link, it takes them to a page that displays the entire news item.
I want the ability to specify a redirect on some news items. If a news item has a redirect, whenever a person clicks on the read more link in the home page, they will be redirected to a different url, NOT the url of the actual news item. And if a person types in the url of the actual news item, they will be redirected to the different url instead.
How do I implement this kind of functionality?
