It can send HTTP 'instructions' to redirect to a new page, force a file to download, respond to if-then-modified headers and decide to change the HTTP status of a file to 304 (Not Modified) or any other HTTP status code (200, 301, 302, 404, etc), it can declare the size of a document in bytes, the last time a file was updated, or change it to a specific type for images, spreadsheets, HTML, sound, video, and more. It can be used to change cache settings for files and webpages on your server.
I've even used it as a really geeky joke to add header information to a file transfer, which is never really looked at by those receiving the files..."x-Joke-Of-The-Day: A man walks into a bar..."
In other words, it can be used to control a lot of really cool functionality and optimizations on your website using HTTP Scripting.
