Not sure if this is possible, but I am wanting to make subdomains be  
redirected to specific folders dynamically via the nginx.conf file. so  
my DNS would point \*.domain.com to the server. and depending on what the  
person typed in for the subdomain, for example [folder1.domain.com](http://folder1.domain.com) it  
would point them to ~/public\_html/folder1 for the site files.  
[folder2.domain.com](http://folder2.domain.com) \>\> site files in ~/public\_html/folder2.

So if the folder exists, it goes there otherwise, goes 404.

Is this possible to pull off dynamically?

Thanks for thoughts on this.

Something like this should work:

server {  
server\_name ~^(?).example.com$;  
root /path/to/public\_html/$domain;  
}
