Caddy Tar Pit

README.md

This is a silly snippet of caddy config file to send heavily compressed huge files to clients prodding "stupid" URLs. (idea from https://tech.lgbt/@becomethewaifu/111879788755441482)

This needs a directory with 3 precompressed files, which may be created like this (tune numbers if you have more/less bandwith to spare or want to annoy "visitors" more/less):

dd if=/dev/zero bs=1M count=10240 status=progress | gzip -9 > 42.gzip
dd if=/dev/zero bs=1M count=102400 status=progress | brotli > 42.br
dd if=/dev/zero bs=1M count=102400 status=progress | zstd -9 -T0 > 42.zstd

I got these compression ratios:

File Compressed Uncompressed
42.gzip 9.937 MiB 10 GiB
42.br 82.032 KiB 100 GiB
42.zstd 3.17 MiB 100 GiB

Since the commands to create the compressed files can take quite a while to run, I'd recommend adding status=progress to the dd command so you actually see how far it is :3
