  Reverse Proxy / URL rewrite upon Request Header

  Oct 28, 2016 12:58 PM|flostony|LINK

  Hi!

  I've got 2 Servers with 1 Public IP and 1 Domain running IIS with same Web API  but one is the production and one the beta server. I want to redirect the request internaliy to the production or the beta server upon a request header.

  for example:
  X-Environment = Production or
  X-Environment = Beta

  Is this possible to achive with ARR?

  sure you can create urlrewrite based on any header to route to any server farm.

  but also consider that your solution is very poor security standards anyone could add these headers in.

  Better to base it on the clients IP address.

  Hi flostony,

  You could pattern the request header by adding the following section in you rewrite rule::

                      <conditions>
                          <add input="{HTTP_X_ENVIRONMENT}" pattern="Production" />
                      </conditions>

  Besides, you could try to configure reverse  proxy based on x-environment header with the following link:

  https://www.iis.net/learn/extensions/url-rewrite-module/reverse-proxy-with-url-rewrite-v2-and-application-request-routing

  This rewrite rule could be a demo to send the request to different server.

  <rewrite>
      <rules>
          <rule name="Reverse Proxy to webmail" stopProcessing="true">
              <match url="^webmail/(.*)" />
              <action type="Rewrite" url="http://localhost:8081/{R:1}" />
          </rule>
          <rule name="Reverse Proxy to payroll" stopProcessing="true">
              <match url="^payroll/(.*)" />
              <action type="Rewrite" url="http://localhost:8082/{R:1}" />
          </rule>
      </rules>
  </rewrite>

  Best Regards,
