Hi all, First, I am not sure, if this is right forum for this topic. I was looking on net, and it seems there is not real forum regarding just CPALad. I got high-traffic website, I need to integrate CPALead (and now I am sticking with Adscend media). My website offers downloads. I am using memcache to cache ALL the html page, so when non-logged user come, I am serving cached webpage, where I can not change anything per user. I want monetize traffic only, when user downloads 10th file, 20th file and so on. It is possible to implement CPALead like this: - user will click http://mysite.com/download/123456 - php code is running behind, and I check if it is 10th download for user, if yes, I will serve some page (CPALead), where user have to fill out the survey and so on, and if done, I get some code back, survey is done and I will let him download (using postback, or there is more simple way?) Thanks for any help.
