If you want to redirect the user to the website where it was create then you can not use the "article sharing for JMS" but insert a link with a the full URL.
The problem is that most of the editor may replace the full URL by a relative path when the domain is identical to the domain that create the link. (ie. if you create a page on
www.domain.com and that you put a link like
www.domain.com/page.html will be replaced by "page.html" because
www.domain.com is identical).
With JMS, if you create 2 differents domain (or sub-domain) that are synonym, you could create the page on a special "editor.domain.com" that will insert a link "
www.domain.com/page.html" in this case as "editor.domain.com" and "
www.domain.com" are different, that keep the full URL in the link (
www.domain.com/page.html).
So the idea is to use 2 differents domain where one is used to create the page and insert the link on the other one. As they are synonym (the same site), this will allow create a full URL instead of a relative path.
