ARR reaction based on URL Rewrite rule result

Hello,

Is there a way to create an action rule based on the result of another url rewrite rule?

I'll give you an example:

I have installed ARR so I configured server farms and some url rewrite rules that they perform a redirect (route to server farm action) to a specific server based on the farm created.

What I'd like to do is to analyze the GET or POST requests and check the result of the rule and if I'll get (ie) HTTP status code 500 then route the request to another farm.

How can I do it?

Can you give me some possible solutions?

Thank you very much

Bye
