Hi everyone,

This is my first time installing nginx. I install it on my Debian
5.0.3 VPS and use Debian's repository to install it (version: 0.6.32).

I'm having problem with using regular expression at server_name.
Here's my configuration:

server {
  listen    80;
  server_name    ~^(.+)\.mydomain\.com$;
  location / {
    root    /home/$1/public_html;
    index    index.html  index.htm;

When I hit, where
/home/myusername/public_html/ is exist. It gives me a 404 error. And
when I view the log file, seems like $1 is null or something.

2010/10/14 10:47:08 [error] 4924#0: *3 "/home//public_html/index.html"
is not found (2: No such file or directory), client:,
server: ~^(.+)\.mydomain\.com$, request: "GET / HTTP/1.1", host:

Am I doing wrong?
Any helps will be appreciated, thanks in advance.
