We need to convert these into the hostname of the reverse proxy server, and have them look like.
If these are sent to the browser as is, the end user will not be able to access the resources these links point to simply because the browser does not know where is located and how it can be reached. These responses may have absolute hyperlinks inside and other information which contains the hostname of the backend server. While still in the same configuration window, we also need to provide information to take care of the responses that will be emitted by the backend server and will transit the IIS server on their way back to the requesting browser. Now we can proceed to fill in the routing information based on the diagram above in the Wizard window that is provided to us. Select the URL Rewrite Icon from the middle pane, and then double click it to load the URL Rewrite interface.Ĭhose the ‘Add Rule’ action from the right pane of the management console, and the select the ‘Reverse Proxy Rule’ from the ‘Inbound and Outbound Rules’ category. Open the IIS Manager Console and click on the Default Web Site from the tree view on the left. Setup a Reverse Proxy rule using the Wizard. This icon is present at the level or each site and web-application you have in the server, and will allow you to configure re-write rules that will apply from that level downwards. Once the module is installed in IIS, you will see a new Icon in the IIS Administration Console, called URL Rewrite - you may note that Url Rewrite is also an add-on that can be installed separately, but that ARR uses functionality provided by Url Rewrite to allow the server to act as a reverse proxy.
You can also download the extension from IIS.net. Just search for ‘URL Rewrite’ in the search options and click ‘Add’.
With Windows Server 2012 R2 or later versions of Windows Server 20, you can use the Microsoft Web Platform Installer 5.1 (WebPI) to download and install the URL Rewrite Module. The first step is to install the add-on module for Application Request Routing for IIS. Install Application Request Routing (ARR for short) I would like to take you through the configuration steps required to setup such a system, where requests are routed via the IIS server to the backend application server and the re-written back again with the public host-name of the IIS server and sent back to the connecting clients.
Route these requests to the backend application server using HTTP.Take in requests from the end users for content from this application using SSL.We want IIS to perform the following tasks: Scenario: Setting up IIS with URL rewrite as a reverse proxy with SSL offloading for a backend service.ĭetails: suppose that we have a web-application hosted on one of our backend web-servers, IIS or another web server, and that this application server cannot be configured to use SSL and is not accessible to the end users because the end users do not have access to the network the server is on.
There are a lot of articles on how to use IIS and URL Rewrite as a reverse proxy, but I have found that many are incomplete with regards to real world scenarios from today’s web applications. A reverse proxy is a network device that takes in traffic coming from the Internet (for example), and forwards this traffic to a backend server on your private network, allow that backend server to be accessible to people who are not necessarily connected to your network. Application Request Routing, one of the many modules that can be added on to the IIS web-server to make this a very versatile tool can be used to perform a variety of tasks, including allowing you to setup your IIS web-server as a reverse-proxy server to some other back-end HTTP service.
