# IIS configuration

## What you need:

Below are what you will need to complete this setup

* The IP address for your instance: This will be provided by us
* The path or list of paths that your pages will be hosted under

## Proxy Setup

This guide describes the configuration options area where you would setup the Proxy pass to our backend systems: <https://blogs.msdn.microsoft.com/friis/2016/08/25/setup-iis-with-url-rewrite-as-a-reverse-proxy-for-real-world-apps/>

Using the IP address of your instance, you would configure the following options:

* IP Address/Port: `<YOUR IP ADDRESS>:80`
* Enable the option *"Enable SSL offloading"*
* Disable the option *"Rewrite the domain names of the links in HTTP responses"*

## Restrict only sending us specific paths

Since you will only be sending us certain paths using this URL rewrite, you should setup a filter so that this URL rewrite only gets applied to a regex pattern. Example would be regex pattern `^(img|stat|style|your-page-path)/(.*)` to filter the requests to send us old these paths.

In addition to the default paths `img|stat|style`, `your-page-path` would be replaced with the pages you want to host with us.

## Host header

We will also need you to configure the server to preserve and send us the "Host" header so that it sends us `www.yourdomain.com` on the requests so that we can load up the correct site and page.

You will need to enable the configuration to "preserveHostHeader". Here is a stackoverflow article describing this: <https://stackoverflow.com/questions/1842885/modifying-headers-with-iis7-application-request-routing>
