It does not work with facebook anymore! I have been trying to do this for the past week. Sometime in the past 2 weeks facebook patched everything to do with cloaking and hiding your url. You can not redirect your url, cloak, metarefresh,NOTHING.
Cloaking is the mischievous art of showing one page to the Facebook approvals team, and another to the unlucky guy who clicks on your ad. When cloaking Facebook, you can launch a series of pant-wettingly lucrative ads simply by ignoring the strict editorial guidelines that the rest of us are obliged to follow.
Naturally, Facebook doesn't take kindly to having the wool pulled over its eyes. If you are caught cloaking ads, you can consider yourself banned, along with any other accounts that you may already be linked to.
