<p>

  If you're using Mono via FastCGI with nginx, and you just upgraded to nginx 1.0, you may be 

  experiencing a 404 on the default page. Or at least I was, on both of my apps that use 

  ASP.NET MVC (one uses 2 and one uses 3, I'm a glutton for punishment).

</p>

<p>

  Specifically, the error was about not being able to find a controller for the

  name "/Default.aspx/Default.aspx".

</p>

<p>

  Anyway, the fix is to remove all traces of <code>index</code> and <code>fastcgi_index</code>

  from your conf:

</p>

<glacius:code lang="nginx"><![CDATA[server {

  listen 80;

  server_name example.com;

  location / {

    root /var/www/example.com;

    index Default.aspx;

    fastcgi_index Default.aspx;

    fastcgi_pass 127.0.0.1:9000;

    include /etc/nginx/fastcgi_params;

  }

}]]></glacius:code>

becomes

<glacius:code lang="nginx"><![CDATA[server {

  listen 80;

  server_name example.com;

  location / {

    root /var/www/example.com;

    fastcgi_pass 127.0.0.1:9000;

    include /etc/nginx/fastcgi_params;

  }

}]]></glacius:code>

<p>

  I may have just had it misconfigured, but maybe it'll help somebody else.
