Warning
This is super-duper bad code. It is not worth using in the modern age, and not worth fixing either. Please do not use this ever.
There aren't known vulnerabilities, but that doesn't mean they aren't there. And this has a habit of somehow timing out connections in weird, niche scenarios. Not cool.
If you really want to use a webserver written by me, use SpruceHTTP, which is way more robust.
Version 4 of JoshieHTTP, now in beta permanent retirement.
