I have a Windows Server 2012 R2 Standard (x64-based processor), and it has IIS 8. I need to configure reverse proxy on it, and it is missing the URL Rewrite module. From what I have read, URL Rewrite requires the Application Request Routing (ARR) module, which itself also requires the Web Farm Framework module and External Cache module.
For URL Rewrite, I can download from https://www.iis.net/downloads/microsoft/url-rewrite
For ARR, I can download from https://www.iis.net/downloads/microsoft/application-request-routing
Where can I download Web Farm Framework and External Cache modules for IIS 8? I have searched and what I have found so far are only for up to IIS 7.5.
