Can download multiple times, but only from the same public IP.

[newAM]

I am not sure if this is a feature or a bug; I figured I should open an issue incase it is a bug.

The site says "Files are stored for 3 days and can be downloaded only once." However, I was able to download a file multiple times from the same public IP. When I attempt download the file from a different public IP I get a 404.

Steps to reproduce:

1. echo 'hello' > hello.txt
2. curl bashupload.com -T hello.txt
3. Copy URL returned
4. wget <the_url> <-- first download works, this is expected
5. wget <the_url> <-- second download works, this is unexpected
6. ssh server_with_different_public_ip 'wget <the_url>' <-- 404, this is expected
7. wget <the_url> <-- 404, this is expected

Thanks for running this!
