Hello Friends,

I have a requirement where a user can configure there own domain.

For example

We will provide a subdomain to every user who will get registered to our  
site.

For e.g [xyz.example.com](http://xyz.example.com)

But if the user already have a domain for example [xyz.com](http://xyz.com) he can point  
that  
subdomain to [xyz.example.com](http://xyz.example.com).

So when someone access [xyz.com](http://xyz.com) internally he should redirect to  
[xyz.example.com](http://xyz.example.com).

Please help me to configure the system

Thanks

Abhis

Let’s say my domain is ‘intridea.com’. Here are some examples of the use  
of  
the :subdomain option:

url\_for(:controller =\> “my\_controller”,

```
    :action => "my_action",
    :subdomain => "awesome") # =>

```

[http://awesome.intridea.com/my\_controller/my\_action](http://awesome.intridea.com/my_controller/my_action)

hello tommy

Thanks for your reply, But I guess I should be more detail with my  
requirement.

We are providing a service where a user can sign up and have there blog  
and  
by default we will provide a separate subdomain to ever user  
[myblog.blogexample.com](http://myblog.blogexample.com) but if user wants they can replace with there  
domain

for e.g.  
[myblog.com](http://myblog.com) which will be actually a pointiing to [myblog.blogexample.com](http://myblog.blogexample.com)

thanks for any help.

Thanks  
Abhishek S.
