What's the best technique for redirecting URLs?

Hi guys!

Because of the structure of my website and for tracking purposes, I need to redirect all my affiliate links, I'm not looking to cloak or hide them, just redirect them.

I'm thinking about using this PHP Redirect technique as explained at http://php.about.com/od/learnphp/ht/phpredirection.htm

I have two questions:

Do you think affiliates would get "mad" at me for redirecting their links?

Do you think Google and other search engines would penalize me for redirecting links? Note: All the links I want to redirect have the nofollow attribute.

Thanks in advance!

 

That is fine....just PHP redirect....or you can use a 3rd party.

 

Thanks, affiliatebugwig.

I'd like to hear more opinions from other users.
