Problem with rendering cookie "_mkto_trk" and pre-fill in _mkt_trk input hidden field.

[Anonymous]

Hi,
 

I tested http://www.exoplatform.com/company/en/products by observing that I was cookied, deleting the cookie and refreshing the page: each time I got a different tracking token. Is this working as you'd expect?

My problem is sometime it cannot render the cookie.

On my Setting:

“Do Not Track” Browser Request:

Ignore

Thanks

Google PageSpeed Insights complains that munchkin expiration is not set.  
 

• http://munchkin.marketo.net/149/munchkin.js (expiration not specified)
• http://munchkin.marketo.net/munchkin-beta.js (expiration not specified)

You can see my results here. How can I get browser caching to work for munchkin?   
thanks,
