nginx reverse proxy proxy_pass weirdness

[deeztek]

I have a nginx reverse proxy to forward requests to various Apache websites
behind it. This all seems to work fine unless I remove one of the proxy_pass
configurations from nginx. Even though I remove it, nginx still fowards the
requests back to Apache to a seemingly random website this time.

I can't seem to get it to stop doing that. Any idea what's going on?
