Hello folks,

half way through configuring nginx I ran into a challenge I did not find a solution for, yet. Your help is greatly appreciated! I want to use the name of a given (but not known as there are many) subdomain by extracting the first three characters of the subdomain to build a directory path, e.g. an user requested to access http://world.wide.com/web.html. The file web.html now resides underneath the directory /srv/www/htdocs/wide.com/w/o/r/.

server {
listen 80;
server_name *.wide.com;

if ($host ~* "^([^.]+(\.[^.]+)*)\.wide.com$"){
set $usr $1;
}
...
}

Is it possible to extract "/w/o/r" from $usr which is set to "world" in the example above? If so how? I tried $usr(0), $usr[0], $usr{0} to access the first character and nothing seems to work.

If this does not work what would be an alternative? Please give me advice!

Thank you,
Fabio.

This is actually fairly easy as soon as you learn of [i]Embeddable Perl[/i]. Your nginx binary has to be configured with --with-http_perl_module to support Perl this way.

Once that is done you can do something like that:

[code]
http {
perl_set $storage_path '
sub {
my $r = shift;
my $host = $r->header_in("Host");
return join "/", split(//, substr($host,0,3));
}
';
}
[/code]


In the server directive you can access the previously set $storage_path, e.g.

[code]
server {
location ~ /matchsomething$ {
root /srv/www/htdocs/$storage_path;
}
}
[/code]


HTH someone else,
Fabio.
