How is that supposed to work? Should something like that here set that
server to be the default if no match is found for the host requested?

server {
listen 80 default_server;
}

listen 80 default_server;
}

Yes, this parameter sets default server for given listen pair, “*:80” in
this case. Actullay, “default_server” is just alias to a “default”. I’ve
introduced this name, because people treats the “default” parameter in

listen 80 default backlog=1000 …;

as related to backlog, etc., although it means just default server for
given listen pair.

Does not work over here. I get a error in Firefox telling me something
about the page not being correctly redirected.

Could you create debug log ?

Are you sure that it is this file ? This error message should be issued
for this:

listen default_server;

I don’t have that there. I have the 80 in front of default_server. The
funny thing is that now I updated all the servers (backend as well) to
0.8.21 and the error is gone. And Firefox was right about the
redirection error:

Looking again at the config file I detected a stupid error. I had this
in place:
1 server {
2 #====================================================
3 set $vhost “domain.tld”;
4 set $vhost_root “/var/www/vu-hosting/$vhost”;
5 listen 80 default_server;
6 server_name www.domain.tld .domain.tld;
7 access_log /var/www/vu-hosting/domain.tld/logs/access_log
combined;
8 error_log /var/www/vu-hosting/domain.tld/logs/error_log;
9 root /var/www/vu-hosting/domain.tld/htdocs;
10 #============================================
11 if ($host !~* "^(..)?(domain.tld)$") {
12 rewrite ^/(.
)$ http://$host/$1 permanent;
13 }
14 #============================================

This produces a loop. Stupid me! Checking if $host is not equal to
domain.tld and then rewriting the url to $host. Stupid! Stupid. The
right config should be:
1 server {
2 #====================================================
3 set $vhost “domain.tld”;
4 set $vhost_root “/var/www/vu-hosting/$vhost”;
5 listen 80 default_server;
6 server_name www.domain.tld .domain.tld;
7 access_log /var/www/vu-hosting/domain.tld/logs/access_log
combined;
8 error_log /var/www/vu-hosting/domain.tld/logs/error_log;
9 root /var/www/vu-hosting/domain.tld/htdocs;
10 #============================================
11 if ($host !~* "^(..)?(domain.tld)$") {
12 rewrite ^/(.
)$ http://www.$vhost/$1 permanent;
13 }
14 #============================================

The right config should be

 server {
     listen  80 default_server;
     server_name  _;  # just nonexistant domain name
     rewrite    ^   http://www.domain.tld$request_uri? permanent;

 server {
     listen  80;
     server_name  .domain.tld;
                 # www.domain.tld is matched by .domain.tld;
     ...
 }

    server_name  .domain.tld;
          # www.domain.tld is matched by .domain.tld;

so that is shorthand for server_name domain.tld www.domain.tld; ?

No. .domain.tld is shorthand for domain.tld and *.domain.tld.

“the first two above” perhaps?

I put it in parens - I think that explains it

i figured someone would link the wiki however if you look at the
language in there it is a bit confusing
