I see that other than the content locker from specific CPA companies or content locker Pro, no free content lockers seem to work properly? while content locker pro is selling for $97. My impressions is that those free lockers cannot detect the final click. The click can be easily detected from the server side of the CPA companies. instead of detecting the final click, those free ones simply put a time delay in there, so even though the visitor does not finish and submit an offer, the content will still be unlocked. so to write a properly working content locker, i have to figure a way to detect the final submission click. Is that right?
