Is it possible to port cookies?

Hi Matt.
Cookies are stored locally on browsers so you do not have access to your clients' cookies. 

For a lead to be cookied on your new domain, they will either have to fill out a form on that domain or click on an email link that directs them to that domain. It is also possible to give a lead a cookie with an associateLead API call. This is especially useful if users login to your website.

Best,
Will

Will,
Sorry - potential rookie question here but... Since the cookies are encrypted via Marketo, can't Marketo read across domains?

Thanks

My understanding of cookies is that, for security reasons, they will only work for one domain. There is some custom scripting you can do (http://stackoverflow.com/questions/315132/how-do-i-use-cookies-across-two-different-domains) but it is generally not advised as this is an exploitable security risk. 

Hi All, 

I am going to run Webinar campaign.In that i need to track the URL parameter and i need to pass the value through cookie to the hidden field in the form.

The Form field name is :Webinar_source.

Please help out by providing script.
