Hello STM!
"Meta refresh" "hide referrer" "jquery javascript"
I find this terms quite often but I'm not sure of having understood their meanings and what are they useful for.
Especially Jquery javascript, I see it in the landing pages I rip and I know that they can contain a redirect script but I don't know what other use they have
Can somebody explain? 
Thank you 
I suck at tech stuff. But since nobody has replied yet, let me put one in the bank first, and maybe someone more knowledgeable will give better answers later.
When a visitor clicks from your lander through to the offer page, the advertiser will be able to "see" that they have come from your particular lander url - also called the "referrer".
Now, if you're not wanting the advertiser to know what your lander url is (e.g. if you're running non-compliant), then you would want to "hide the referrer" or "blank out the referrer".
A convenient way (although not foolproof) of doing this, is through what's called the "Double Meta Refresh" or DMR for short. It's like refreshing the page twice so that the referrer information disappears, so that the advertiser won't be able to see the referring website (i.e. your lander).
Some trackers like
If I remember correctly though, DMR will cause some degree of clickloss, possibly due to a delay in redirection of the visitor.
Here are a couple of forum threads on the topic you may find useful:

As for jquery and javascript - they are necessary for programming lander elements that involve interaction with the visitor, and/or some sort of animation. So stuff like the spinning wheel, questionnaire questions that appear and disappear as the visitor clicks on answers, auto-updating "facebook comments" - all require JS/jquery.

Hope that helps!

Thank you very much guys, that's clear now. With all this said it's better to run compliant because all this refresh and redirect makes everything slower
