Basically what I'm asking for is exactly this: How to set up IIS request mirroring to staging environment? but since noone has responded to that thread (and it's been there for years), I'm creating another question.
Explanation: We have a bug in production which is a very strange issue, probably not even related to the code but we need to nail it anyway. Our only idea is to mirror(duplicate/replay) every request that comes to production, to the staging environment which is basically a copy of production (app+db). This way once we see the bug, we'll, hopefully, see it in both envs which gives us a lot of time to investigate - right now we need to recycle entire production app in order to make it work again.
Is there a way to do this in IIS without making code changes?
