apache redirect

["Mandy Singh" <mandys@xxxxxxxxx>]

Hi,

 

I would like to learn how to redirect a subdomain on my website back to the parent site once again.

 

Eg:

 

My main site is: www.example.com

 

I created subdomain.example.com

 

Now I want that when user types subdomain.example.com in the url bar it goes to www.example.com

 

Want to learn 2 things -

 

1) Redirection without url bar url getting unchanged

 

2) Redirection with url also getting changed to www.example.com

 

What's the best way to do this?

 

At how many levels can this happen (DNS, Apache, etc)?

 

Which the best place to do this?

 

Any good documentation (easy to understand redirection doc somewhere)?

 

Let me know.

 

Thanks in advance,

Mandy.
