yeah, I think I actually wrote that about eight years ago and 
then never revisited it.... actually git blame says "committed on 
Mar 24, 2012" so almost nine! And indeed, that git blame shows 
the bulk of it is still the initial commit, though a few 
`toLower`s got changed to `asLowerCase` a few years ago... so it 
used to be even worse! lol

But wanna see something that will make you cry?

I have another http header parser!!! That's for my client, and as 
you can see, it is... not great. The case-insensitivity for 
example is a mega hack and I actually need to fix that eventually.

At least there's some support for line continuations there. I 
don't remember if I ever actually tested that though, it seems 
most clients and servers don't do that anyway.
