Setting Access-Control-Allow-Origin header on source server

Question

I am using $.get to parse an RSS feed in jQuery with code similar to this:

$.get(rssurl, function(data) {
    var $xml = $(data);
    $xml.find("item").each(function() {
        var $this = $(this),
            item = {
                title: $this.find("title").text(),
                link: $this.find("link").text(),
                description: $this.find("description").text(),
                pubDate: $this.find("pubDate").text(),
                author: $this.find("author").text()
        }
        //Do something with item here...
    });
});

However, due to the Single Origin Policy, I'm getting the following error:

No 'Access-Control-Allow-Origin' header is present on the requested resource.

Fortunately I have access to the source server, as this is my own dynamically created RSS feed.

My question is: how do I set the Access-Control-Allow-Origin header on my source server?

Edit

I'm using PHP and I think my webserver is Apache.

What server-side language are you using? What webserver are you using? — user400654

You have two options. Add a .htaccess file that sets the header, or have php return the file with the header. Plenty of examples here: enable-cors.org/server.html — user400654

Set it right in the php:

header('Access-Control-Allow-Origin: *');

This worked great for me. Is there any security advantage to having the access in the single php file over adding it to .htaccess for the site?

For apache, you simply add this to a .htaccess file in the same directory as the file you are trying to access remotely.

Header set Access-Control-Allow-Origin "*"

Turns out the PHP option worked for me in this instance (header("Access-Control-Allow-Origin: *");), but thanks for this answer.
