I also could not find the ARR icon when using the server manager. But when I went to control panel, admin tools, iis manager, the ARR icon was there.

Server Farms should be the UI branch from which it's configured. The top level of a given farm shows its ARR properties. If you haven't closed/reopened the Inetmgr GUI since installing it, you need to do that too.

Without the SSL on the proxy, your ARR server won't even be able to read the request headers, including the HOST and the URL requested. It could only blindly redirect all traffic to the web tier servers. Check out Won Yoo's blog post regarding ARR & SSL Offloading (and not offloading). The guy wrote ARR. http://blogs.iis.net/wonyoo/archive/2008/07/10/...

You don't want to setup IIS using clustering services. This is not what Windows Clustering is for. At it's core, Windows Clustering is for restarting a service if it crashes-- but with the ability to restart the service on another machine if the machine fails. You will not achieve any of your goals and you will confuse the heck out of everyone. You ...

I got this problem on Server 2012 R2, I usually start IIS Manager form the command line It turned out when using: %windir%\System32\inetsrv\iis.msc the ARR icons are missing, but when using %windir%\system32\inetsrv\InetMgr.exe they show up just fine. On Server 2012 R2, both Administrative tools and Server Manager use InetMgr.exe, so both should work, ...

Your Action is set to Rewrite so it is rewriting the URL. In IIS Manager: Right-click Server Farms, click "Create Server Farm". Give it some name. Put the fully-qualified domain name to your Tomcat instance in the "Server name or address" field Click "Advanced settings...", expand "applicationRequestRouting" and change httpPort to 8087 Click "Yes" when ...

You can use a custom rewrite provider. A provider is C# code that turns one string into another string. You can then use it in a similar way to how you'd use rewrite map: You can pick a separator which is not valid in a url at all. (Maybe use space or something like that. I'll use | so it's visible in this post, but you should pick some other string.) You'...

After some months since I asked this question, I should probably write an answer myself... We've been working with the setup as described in the question, and it actually works as expected. The only problem is, that the cache hit statistics just show some arbitrary information. I haven't been able to find out what it tries to show, but in my experience, it ...

We had typo'd HTTP/srvarr and HTTP/srvweb as http://srvarr and http://srvweb. Make sure you do it as the protocol instead of the url! Also settings that might help others: Remove both NTLM and Negotiate and add Negotiate:Kerberos and turn on UseAppPoolCredentials and off useKernelMode Make sure all of the servers are using your domain web service account ...

This will change the OS defaults in a way to allow all TLS versions (or even SSL if you choose). I tested this on ARR Windows 2008 R2. Windows Easy Fix Patch

I am running ARR 2.5 on a Windows 2008 R2 Datacenter SP1, and have experienced the same problem when transitioning a farm server by selecting either "Disallow New Connections" or "Make Server Unavailable Immediately". The controller will eventually revert the farm server to available. I checked the access logs on the affected server and in one case, it ...

The bindings on a website take higher priority than the URLRewrite's, so my Site was answering before URL_Rewrite could pass to ARR

If this is a single server and if you're running PHP on IIS where it's installed and configured as per the guidelines (PHP non-threadsafe build + FastCGI) then I can't really see a reason to be adding ARR into the mix unless.... you have Apache for Windows installed and are running your PHP applications in Apache but want to use ARR as a reverse proxy You ...

Geograpic load balancing (sometimes called "Global Server Load Balancing" or GSLB) as traditionally done has little to do with web servers, and everything to do with DNS. You need a DNS server that will give people the IP they want based on their geography. See pGeoDNS for a simple example written in Perl that will run on most systems, and uses a free ...

Please see the bellow tutorial http://learn.iis.net/page.aspx/486/http-load-balancing-using-application-request-routing/ and for more information you could go here http://weblogs.asp.net/owscott/archive/2012/04/19/google-and-geo-location-cnds-dns-load-balancing-week-50.aspx where it's explained exactly what you want to accomplish and for the whole series (it ...

Get a network packet capture of the failed requests and check the Http request header for the kerberos authentication token. If you are expecting a kerberos token and it isn't present, the issue probably isn't your servers. I'm assuming you are expecting kerberos because of the SPN checklist. Refer to the following for more information: https://...

On the ARR server you will want to configure a single farm that contains both web servers. Keep the default rewrite rule that ARR creates automatically. On the web servers you will create a website in IIS for each application you are wanting to serve. Each site in IIS will need its bindings set to all IPs (*) with the hostname that matches the site you ...

First of all, I don't know the answer but am guessing it does at least use session id. Second I would go about finding out not by looking at documentation which may or may not be trustworthy on such a detail, but by sniffing the traffic and in such a way ensuring a 100% correct answer. I find this the easiest way when it comes to proxies which can ...

Answering my own question after using Wireshark to determine the answer. Yes, AAR will utilize SSL sessions and those sessions can service multiple clients. Using Wireshark I observed the following: Client1 -> AAR GET /foo AAR -> ContentServer Client Hello ContentServer -> AAR Server Hello, Certificate, Server Hello Done AAR -> ...

Typically you would have ARR on the NLB level, directing traffic to the 2nd level Content servers in the farm who serve the same/shared IIS config (same applications). See Achieving High Availability and Scalability - ARR and NLB In your scenario, you don't really need ARR - you just want to NLB between 2 content servers, which will allow for 1 server to ...

Let me answer my own question... I disabled "Require Server Name Indication" and suddenly everything worked. This is weird because SNI was enabled on all servers in the farm for the same site but for one of them, unchecking it made it all work. My theory is this: Even with shared config, SSL binding information doesn't really transfer from one server to ...

UPDATE Microsoft has released a patch and associated workaround steps since this answer was submitted. Please see newer answers and comments for details. It turns out that the answer is no, it is not possible. The following response from Microsoft IIS/ASP.NET Developer Support clarifies the technical details.

According to this comment on Scott Forsyth's blog, this can happen when you have a web farm on a server with multiple app pools: The problem is that ARR doesn't have a dedicated worker process to do the health testing with, so it just uses ALL of the w3wp.exe worker processes. What that means is that if you have multiple app pools, or a web garden, then ...

X-ARR-ClientCert is sent if there was a mutual SSL handshake with ARR. Sending a request via https with the X-ARR-ClientCert header won't be enough as there really wasn't a mutual SSL handshake in that scenario. By a mutual SSL handshake, It means that the browser or client gets prompted for a client certificate and the client provides one. If you want your ...

My Googlefu was failing me today. In the Server Proxy Settings pane of IIS Manager, I needed to uncheck "Reverse rewrite host in response headers".

The best way I've seen to accomplish this is by mixing powershell with the appcmd.exe command. Microsoft has released some sample code for setting up a farm in a docker container here. Here's an example: ForEach($farm in $farms) { # Create the farm .\appcmd.exe set config -section:webFarms /+"[name='$($farm.name)']" /commit:apphost ...

One of the benefits of ARR as of Nov 2014, is the it provides client affinity to your HTTP requests. As of now, the Azure load balancer / traffic manager does not provide this.

In order to let the ARR server know when not to route requests to a server, you need to set up a Health Test. Select your server farm in the IIS Manager Select the Health Test Feature. Here you can fill in an URL to run the health check against, (ie. a text file containing a good word, or the index page on the web site your trying to load balance). Once ...

I had the same problem and the culprit seems to be the "unknown" Availability and Health Status. This is due to not having configured a correct health check for your site in the "Health Test" section, a url that can be tested to detect if the site is online. Once configured the status will change from "unknown" to "Healthy" and you will be able to do a ...
