413: Request Entity Too Large with nginx

I'm working on a big site, importing a lot of files to a WordPress installation and started to get a bunch of 413's. After a little bit of googling I found out what was happening:

What needs to be done is on /etc/nginx/nginx.conf write:

http {
    client_max_body_size 20M;
    include       /etc/nginx/mime.types;
    A LOT MORE SETTINGS...

Yes, just add client_max_body_size and restart your webserver. This by default is 1M, so anything beyond this will be refused.

Any comment goes best to my twitter here.
