How safe is double meta refresh? (7)

How safe is double meta refresh?

Sup!
How safe is double meta refresh? I've heard that it can leak the referrer, but is that really the case? What % of visits can leak if so? We are speaking mobile where plugin & addon combo is not an issue
Is it more like 0.1% or 0.00001%

I'm using Voluum built in DMR

It depends on the browsers/devices.

The DMR and SSL > non-SSL are 100% fine as long as the browser/device follows the relevant HTTP standards, so the problem is with the traffic itself, not the technique.

In other words I have no idea.

I suppose one way you could check for specific campaigns is do a manual meta-refresh to a page that logs referrer then meta-refreshes to your affiliate link. After logging x amount of referrer info you could check the logs and decide whether you trust it enough.

@Zeno - do you use double refreshes and if so, how do you implement that technique? And don't you lose some analytical and/or Tracker data doing this?

I don't know the % exactly since I never measured but I would say it's pretty safe.

I've been using it on campaigns doing 1-2 million clicks a day for months and nothing was passed ( I know since the network would have hit me up 100% if they saw the lander I was using ).

if its properly coded, the DMR should never pass your referer since the second refresh should be checking the refer, and if its not blank, redirecting to another page instead of the offer.

rumors of leaks are from regular single meta refreshes, in which case the second refresh, the one that does the checking, isnt present.
and you will also lose traffic using DRM, because all the ones that do not pass onto the offer because they didnt clear, they will be lost to whichever page you redirect them to.

no i dont, i dont use Voluum. but generally they all work the same and usually work something like this:

1 - refreshes page with meta refresh
2 - checks refer to see if blank
3 - if referer is blank, redirect to offer , if not blank retry step 1 and 2, and if still not blank redirect to some other page instead of the offer

also, there are some other similar scripts floating around that clear the refer via a few different ways besides just meta refresh. so it would do multiple ways of clearing before checking and redirecting
