How to create a link to different context?

Hi,
I use several contexts each with its own domain. how can i make a link in each context to the main (web) context?
i tried using [[~4? &context=`web` &scheme=`full`]] but it doesn't seem to generate the context part allright.
this results in
- http://www.domain1.com/folder/mypage.html
- http://www.domain2.com/folder/mypage.html
- http://www.domain3.com/folder/mypage.html
where the domain is the domain of the calling context.. it should be - http://www.domain1.com/folder/mypage.html in every domain
How should this work?

You need a plugin to initiate the desired context. Try ContextRouter, I use it when I need to work with multiple contexts. XRouting is also a good one.

Hi Susan,

I used 'Gateway manager' to setup the context properly. And that works fine. I was trying to make a link form one domain to another by using .
Following the RTFM, https://rtfm.modx.com/revolution/2.x/developing-in-modx/other-development-resources/class-reference/modx/modx.makeurl i tried to pass in the proper context.
The RTFM suggest you can pass that as a property :"Note that the arguments available to this function can be passed to the [[~link]] tags, e.g."
But the proper domain (context) is not rendered into the 'full' schemed URL. ( [[~4? &context=`web` &scheme=`full`]]).
I'm I misunderstanding the RTFM? or am i doing this wrong?
