DTM local storage or Data Element across domains

[snehaa30982388]

Hi,

My website has two different domains. Some pages are in domain 1 and some are in domain2. I have a requirement where I have to read data from a first party cookie in domain 2 and use that data when user go to domian 1  from domain 2. Both domain uses same DTM web property.

I tried session level data element and DTM local storage but no luck. Value of data element / local storage set in domain 2 are not available in domain1.

Is there any solution by which this can be achieved ?. Will  "span across multiple domain" in web property setting help ?

Thanks

Yes. There is a solution that will allow secured data sharing outside of the same-origin constraints of localStorage and sessionStorage.

Can you DM me the details of your situation?

Hi Sneha, were you able to get this taken care of?

Hi Gigazelle,

No not yet.. I tried many options but looks like this is not feasible in DTM or I have not yet found the correct solution !

Thanks,

Sneha

Sneha,

We (Search Discovery Inc) have developed a technology called Storage Spanner that allows you to securely use localStorage across domains.  The solution works in DTM but does not require DTM.  I will soon be building a Launch extension to make it super easy to implement in that environment.

Thanks for the info Stew. I primarily want to use something in build in DTM or Launch.

One thought - I forgot to ask.  Are both domains on the same top level domain? (i.e. www1.foo.com & www2.foo.com are both on the top level domain "foo.com") .  If this is the case you can use a cookie set on the TLD which would span both.

If not, there really is no solution within DTM or Launch to do this.
