How to show different ARR friendly error pages on timeout depending on downstream server

Question

I'm trying to work out how we can go about serving different error pages from within ARR when a timeout occurs (http 502.3).

Scenario is we could host X number of different brands and want to supply different error pages if their servers are down.

The out of the box approach on a 502 error is that it will get the "Default Web Site" error pages, what I'm wondering is way we can provide that functionality without adding a new ARR server every time we bring on a new customer.

Any help you could give would be greatly appreciated.

Kind Regards,

J

Our final solution was deceptively simple. ARR doesn't have this functionality and e need code to allow logic, so we added a .aspx page with the appropriate host to error code mapping. Effectively a dictionary mapping within the .aspx page.
