URL rewrite for ADFS 3.0

Hi,

I am using ADFS 3.0 with RelayState.  The vendor (RP) wants to have the ability to send email to customer with a "deep link".

In ADFS 2.0, you can use URL rewrite to make sure the pattern of the "deeplink" is form correctly since it does use the full function of IIS.  I ADFS 3.0,  IIS is no longer installed so is there a tool that is similar to URL rewrite to resolved the "deeplink" redirection from the vendor (RP).

Thanks,
