MODx with multi context and same data

I'm using the domain x.com(context x) with a number of data. And in near future my friend wants to create other domain y.com (context y), which will use the same data on x. I wonder is there any method to use the data of context x on context y which can point links from domain x.com to domain y.com?
I'm thinking of working a simple seperate loading resource on y.com which will pull the data based on getResources?&context=`x`, use the id to load necessary content. But that should be the last solution if I can't find other way.
The context switch is based on MODX_HTTP_HOST and context settings: http_host,site_url,etc.

I think once working with multi-context with custom template sharing the same data, this should be an issue. I think I'll do the last shot with seperate loading resource with snippet to resolve the uri or id to pull the data.

Still hoping for someone to discuss about this issue.

If the sites are the same, why do you need multiple contexts? Just point both domains at the same content and make sure the site_url or any absolute links are not cached into the pages.

Hi opengeek,
It's so good that I can get a reply from you. The data between two context is partly the same, based on 2 different campaigns. To save time posting again some news or blog post, I think pulling the data from previous context is better. Duplicate content is not good, but at this context, it's good for SEO other campaign, on the same server.
