note: this will also redirect something.example.com to www.example.com

@Piskvor: No, it will redirect it to *www.something.example.com*.

Thanks for the reply. But what does i means R=301?

@basit74: The *R* flag forces an external redirect and *301* is the status code of the response.

Gumbo 2010-02-16 11:47:06

@Gumbo: I stand corrected.@basit74: R=301 means HTTP Redirect with code 301 (Moved Permanently).
