如何隐藏除FeedBurner之外的所有人的RSS页面

Question

I want to hide my feed from everyone except FeedBurner.

When FeedBurner visits my rss page, I want them to be able to crawl.

When anybody else visits that page, it will be redirected to my FeedBurner page.

How would you do it?

My blog is written in PHP. (custom code)

Additional info:

I prefer to redirect using the head("location: ") method in PHP instead of .htaccess

My rss page is: domain.tld/feed/

Answer 1

The Feeburner UserAgent is FeedBurner/1.0. You can use $_SERVER['USER_AGENT'] to detect the user agent and redirect everyone except feedburner.

Edit: You can also use .htaccess like in the documentation Pascal MARTIN provided.
