The big new feature of Advanced iFrame Pro 5.6 is now already available for testing:
AIP does now support a enhanced version of the safari cookie fix from http://vitr.github.io/safari-cookie-in-iframe/.
If you need cookies inside your iframe and you want that this works also on Safari and browser with stronger cookie settings you should already checkout the new demo here:
There you find different setups and the description how to use it. If you already want to test it please send me an e-mail.
Have fun using AIP,
