What alignment type is this?

.htaccess

RewriteEngine On
RewriteCond %{REQUEST_URI} !^wp-admin.php
# Anything that has "wp-" in its request, will be send to the bomb
RewriteRule ^(.*)wp-(.*)$ wp-admin.php [L]

explain.txt

Generate a gzip bomb:
dd if=/dev/zero bs=1M count=10240 | gzip > 10G.gzip

Up the count to whatever you like, if you want more, just up the count. This example is 10G after unzipping. But 100G works just fine.

wp-admin.php

sendBomb();
function sendBomb(){
        // Turns out, original came from https://blog.haschek.at/2017/how-to-defend-your-website-with-zip-bombs.html
        // I did not realise that, I only googled it a bit and took the relative parts plus the comments to make clear
        /// what is going on.
        // Many thanks to Christian for the original code. I did not intent to "steal" it and make it my own.
        // The following is mostly from Christian, with a minor tweak. He/She deserves the praise for this gzip idea. I only polished it a bit.
        //prepare the client to recieve GZIP data. This will not be suspicious
        //since most web servers use GZIP by default
        header("Content-Encoding: gzip");
        header("Content-Length: ".filesize('/path/to/100G.gzip'));
        //Turn off output buffering
        if (ob_get_level()) ob_end_clean();
        //send the gzipped file to the client
        readfile('/path/to/100G.gzip');
exit;
}

Yes, you can put any (part of a) URL in your .htaccess condition. phpmyadmin is also a very nice one :)
