Host header with nginx proxy_pass

Posted on Mar 31 2010

I recently moved this blog and evilstreak’s to a VM on my stonking new server from Hetzner: 24GB. Woo!

But I made a booboo in switching from lighttpd to nginx. It turns out that the proxy_pass directive for nginx overwrites the Host header from the request with the proxy host. This in turn means that jsgi-vhost will fallback to the default host: in this case it happened to be evilstreak’s blog. Oops. The correct config invocation for nginx to preserve the host header from the request is:

server {
    listen 80;
    server_name ashberlin.co.uk;

    location /blog/ {
        proxy_pass http://127.0.0.1:3000;
        proxy_set_header Host $http_host;
    }
}

So to those of you who read my RSS feed - sorry for the confusing posts over night. That’s what I get for playing at being a sysadmin late at night.
