    The Location header is for redirecting the page.

    Actually location option is used to redirect to a new resource as part of processing the request. For example,

     render :xml => post.to_xml, :status => :created, :location => post_url(post)
    

    is telling the recipient that a XML file for the post is created and you will get this from post_url(post). Hence GO THERE ;)

    render method does this by setting the Location option in response object

    ... ... ... 
    if location = options[:location]
        response.headers["Location"] = url_for(location)
    end
    ... ... ... 
    

    You can find details about Location header here http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.30.
