`preserve` is a little HTTP server to preserve the presence of URLs.
Ever relied on an HTTP resource to be available and it vanished? Happened too often to me so I wrote a little tool to prevent URLs from vanishing: `preserve`.
## Usage
After you've started `preserve` it will by default listen on port 3000 and you can start using it by prefixing the URL of the resource:
Lets say you want to ensure the image `https://example.com/image.png` does not vanish:
-`http://localhost:3000/https://example.com/image.png` will fetch the resource once and then deliver it from the local cache
-`http://localhost:3000/latest/https://example.com/image.png` will fetch the resource with every request until it gets unavailable and then serve it from local cache
