# Luzifer / preserve
|
|
|
|
`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
|
|
|
|
This also works with parameters:
|
|
|
|
`http://localhost:3000/https://pbs.twimg.com/media/somemediaid?format=jpg&name=4096x4096`
|
|
|
|
If you do have some service (like Discord) screwing up these URLs you can apply base64 URL-Encoding to them (do NOT omit the padding):
|
|
|
|
`http://localhost:3000/b64:aHR0cHM6Ly9wYnMudHdpbWcuY29tL21lZGlhL3NvbWVtZWRpYWlkP2Zvcm1hdD1qcGcmbmFtZT00MDk2eDQwOTY=`

|
### Select Storage Provider

**Local files**

preserve \
|
|
--listen=:3000 \

--storage-dir=/var/lib/preserve

```
|
|

|
