i have tried to create a material to be transparent to catch shadow and to receive reflection from the objects in the scene but not the world, after playing with material nodes for a while i have found that with the ray length node from light path i can extract a map from the object for transparency visibility of the plane but i didn't found how to use it in the plane only if there was a way to translate that data back into the plane material it would be useful .
another thing that i'd been thinking was to find a way to limit the reflectivity distance of the plane if there was a way to limit the plane from receiving reflections .
i really don't want to dive into post processing process , this is kind of challenge to do it within the cycles ...
so after a while searching i have found this gold link How to make material like shadow catcher, but for reflection(not shadow)?
although it kind of creates what i was searching for but this is not actually the answer to this question because what if the background isn't black ?
