"Route to Server Farm" missing in IIS after installing ARR 3.0

I am trying to configure IIS for a zero-downtime deployment per this blog (green/blue app deployments). I have setup Application Request Routing (3.0) and URL Rewrite, but after setting up the websites and server farm, I see no "Route to Server Farm" option in the Rewrite rules.

Route-to-server-farm This is what I was expecting to find due to the instructions.

I have completed the following steps on IIS 10 (Windows 10) and IIS 8.5 (Server 2012 R2):

  1. Installed Application Request Routing 3.0 (i have also tried with 2.5 unsuccessfully)
  2. Setup 2 different IIS sites for my prod (green) and stage (blue) deployments, and confirmed they are working when directly accessing
  3. Created web farm in IIS and added 2 servers

server-farm servers

  1. When I was trying to setup the URL Rewrite, I expected to see the "Route to Server Farm" action type, but I see only these options:

url-rewrite

Solution

  • The issue was I was trying to add a URL Rewrite rule on the site level instead of server level.
