query string to subdomain

[kent88]

Hi,
I am very new to htaccess so I need just a little help to get me started. I think I would also need dynamic subdomains configured for this.

I would like a visitor to my site to see a link like this to change to a new city:
http://newyork.mydomain.com


the real link: http://class.mydomain.com/index.php?region=245

With the query string to my php/mysql script would be hidden. This is what the script would get.


There are several hundred region numbers each corresponding to a specific city and I don't actually want to create a subdomain for each. I am looking to do this to make the urls friendly and improve SEO. The site will be similar to kijiji or craigslist.

Any help would be appreciated.

To avoid the need for creating each domain manually, you may wish to consider creating a wildcard domain. There's many threads around here covering that topic.

As for displaying the content of something like http://class.mydomain.com/index.php?region=245 without displaying that in the browser's address bar, you would want to use mod_rewrite. The Apache documentation for mod_rewrite is rather comprehensive.
