Question

I have Apache running on port 8097, and Nginx proxying requests to it:

location / {
    proxy_pass         http://127.0.0.1:8097;

    proxy_redirect          off;
    proxy_set_header        Host            $host;
    proxy_set_header        X-Real-IP       $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    client_max_body_size    10m;
    client_body_buffer_size 128k;
    proxy_connect_timeout   90;
    proxy_send_timeout      90;
    proxy_read_timeout      90;
    proxy_buffers           32 4k;
}

Apache config (meaningful part):

    <Directory /home/some/htdocs>
            Options FollowSymLinks
            Options -Indexes
            AllowOverride All
            Order allow,deny
            allow from all
    </Directory>

So what happens: when I go to www.mysite.com/photos and there exists a directory photos Apache redirects me to this directory with slash added. But for some reason it actually redirects me to www.mysite.com:8097/photos/ I see this address in the browser, what I am actually not supposed to:

HTTP/1.1 301 Moved Permanently
Server: nginx/1.2.4
Date: Thu, 01 Nov 2012 10:28:13 GMT
Content-Type: text/html; charset=iso-8859-1
Connection: keep-alive
Location: http://www.mysite.com:8097/photos/

I know I can fix this via UseCanonicalName On (not the best solution – what if i do not have a canonical name?) But still I wonder, how it happens that the actual apache port is exposed with this kind of redirect (but all other rewrites and redirects work properly).

I found a way to fix it in nginx config. One need to add port to Host header

proxy_set_header        Host            $host:$server_port;
