I'm not sure what you mean by Flash redirection... do you mean an actual Flash applet?
Actually, most cloaking scripts I know of do not use "redirection". Instead, they use LWP or Curl to grab the landing page and display it under the cloaked URL. In my opinion, you should try to stay away from redirection, because you don't want the URL to change.
Well, the Forum Charter [webmasterworld.com] prevents us from doing product reviews or comparisons, but I'd stay away from any product that uses a redirect.
It's not that you will see the original URL first, but you're being redirected directly
uh... ok. Redirected directly? I don't get it.
I don't know of any major cloaking software programs that are "scams". I suggest you find ones that offer money-back guarantees or demos and try them for yourself. There are many out there, and they have different features. Find the one that is best for you.
