Our software here has an option for Redirection Pages. These show up between some other pages here on the site. Some examples are when you conduct a search, when you post a reply (not from the quick-reply box), and a few more. Here's what they look like:
The advantage of them is they give immediate feedback that what you've clicked has been properly accepted, and will be processed by the site. The disadvantage of them is that one second (ish) delay based on that other page. I removed them a few years ago because we were having server load issues with these additional pages. But now our server is so overbuilt, that it's really just a preference. I've turned them on for the moment. What say you?
