Hi there,

I switched to nginx 0.7.61 recently and came across some odd vhost issues:


1. Let's imagine the following cgi script:

--
#!/bin/sh
echo Content-Type: text/plain
echo
env | grep SERVER_NAME
--

that is served using fcgiwrap as follows in the nginx.conf:

server {
listen 8080;
server_name a.dom.tld dom.tld b.dom.tld c.dom.tld;
location / {
root /; # html results in 403
fastcgi_pass unix:/var/run/fastcgi/test.sock;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_NAME
/usr/local/bin/printenv;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
}
}

The result is always the first server_name entry, regardless if one
access dom.tld, c.dom.tld or b.dom.tld -- it's always a.dom.tld in the
given example. So I suspect that $server_name is incorrect. A bug?

(I currently have a separate server { ... } section for each
server_name, but I think that's not very great).


2. A second issue is, that the above cgi script is only executed
correctly for me if the server setting:

root /;

is given. If the root is anything else, I always get 403 errors, why
is that? Is this a bug?


3. Finally let's assume I have two domains dom1.tld and dom2.tld and
let's imagine a bunch of sub-domains each:

a.dom1.tld, b.dom1.tld, a.dom2.tld, and b.dom2.tld

Now my requirement is, that [{a,b}.]dom2.tld is ALWAYS redirected to
[{a,b}.]dom1.tld. My current solution is this:

server {
server_name dom2.tld;
rewrite ^(.*) http://dom1.tld$1 permanent;
}

server {
server_name a.dom2.tld;
rewrite ^(.*) http://a.dom1.tld$1 permanent;
}

server {
server_name b.dom2.tld;
rewrite ^(.*) http://b.dom1.tld$1 permanent;
}

How can I achieve this with a simpler setup?


Thanks in advance,
Anselm
