Nginx as apache reverse proxy giving 404's on .htaccess rewrite

Question

I'm trying to use Nginx as reverse proxy with Apache to cache static files, etc. I'm having an issue on a new install, that it's not passing on URIs to Apache. Basically I have a vBulletin forum, and I'm using vBSEO as the SEO proxy. The problem is it's generating 404s for every URL, except files that already exist.

Answer 1

Could you possibly give us the relevant portion of your nginx configuration? A.t.m. we cannot guess what's wrong (although one might: using 'localhost' when not in the hosts file, so not resolving to 127.0.0.1, wrong portnumber for apache, forgetting to add a host header, etc.). Normally, It'd be something like:

server {
    listen       80;
    server_name  www.example.com;

    # normally some checking here for static content which exists as file 
    # like images, js, etc, with a 'break', with at the end:

    location / {
        proxy_pass         http://127.0.0.1:<portnumber apache is on>/;
        proxy_redirect     off;
        proxy_set_header   Host $host;
    }
}

Well I traced it down to the SEO friendly plugin ( vBSEO ). It was producing links with .html extension and it seems nginx had it set for caching. Since those links didn't exist physically, it was producing the 404s.
