Creating subdomains on the fly

["Mandy Singh" <mandys@xxxxxxxxx>]

Hello Everyone,

 

Hope everyone is doing good :)

 

I have seen this on many hosting sites, where you go and register and then you immediately get a url like http://{your_username}.theirdomain.com.

 

I know that this involves 2 steps on my windows box -

 

1) adding an entry in the hosts file

 

2) adding a name based virtual host

 

However, now I have a requirement to do this on linux/apache.

 

Generally it requires a change on the dns end as well as adding a name based virtual host.

 

How can I automate this process?

 

How can I give every user on the site a subdomain as their username?

 

Please let me know

 

Thanks,

Mandy.
