There has been a lot of news this week with Tech Ed North America running and sending out lot’s of information.

Application Request Routing and Server Headers "X-Powered-By: ARR/2.5"
Today I would like to talk about the headers that you get if you utilise Application Request Routing in your environment.
What is Application Request Routing?
If you haven’t used this IIS Extension then you’re in for a treat.
It’s a useful way of allowing you to define how your Web server environment will scale and handle requests.
It also allows you to build a Content Delivery Network and place your content on the edge of your network if needed.
http://www.iis.net/downloads/microsoft/application-request-routing has more on this and it also introduces by saying the following.
”IIS Application Request Routing (ARR) 2.5 enables Web server administrators, hosting providers, and Content Delivery Networks (CDNs) to increase Web application scalability and reliability through rule-based routing, client and host name affinity, load balancing of HTTP server requests, and distributed disk caching.”
When you configure Application Request Routing you will notice that it will send a header back in the request "X-Powered-By: ARR/2.5".
In your environment you might not want to send this header so there are a couple of different ways to remove.
How you remove it will depend on how you are using ARR.
ARR allows you to forward your HTTP Requests in two ways.
