mib two sided material issue

[Caveman]

Hi In this scene I have set a wall with two sided material with a transparent material on the back and a architectural material on the front. The idea is to render the scene through the wall without blocking the camera's view. Everything renders fine except for the Glow effect which get blocked by the wall. Any idea why this is happening?

glow is a post effect and because of that its not possible to get objects into account which are blocked by other objects.
post effects are applied to the whole image after the image is rendered so it does not know whats happen in the scene. it dont know if a object is transparent or reflective or like in this example, that there is an object behind another one.
render in passes and create the glow in post, best way.
