I believe the examples shown in this forum post would also be helpful in understanding how different rules can be used for routing requests: http://forums.iis.net/t/1158459.aspx

Let me know if you have further problems.

You can do this by doing the same as what's above but you wont need any conditions. Instead you should use the pattern in the Match URL section of your rule

RequestedURL: Matches the pattern

Using: Wildcard

Pattern: http://www.iisserver.mycompany.com/internal1/*

In the Action section you should have something like this

Action Type: Rewrite

Rewrite URL: http://internal1.mycompany.com/{R:0}

And finally you can add another rule for your internal2 server

I want to do something similar but also being new to IIS and ARR having problems getting it to work.

Would like to configure an IIS server as a reverse proxy such that I can access internal servers from it.

For example how can I configure it such that

http://www.iisserver.mycompany.com//internal1 would route to http://internal1.mycompany.com

and

http://www.iisserver.mycompany.com/internal2 would route to http://internal2.mycompany.com

as well as rewrite URLs in the responses. I seemed to make it work for one server but then I screw it up trying to add another and then can't even get it working for the 1 server case again.

Any help would be appreciated.

Hello,

Yes you can do that with ARR

In IIS manager click on your server node (not a web site) in the left tree and from there open "Application Request Routing"

On that page check the "Enable proxy" check box at the top. Still on that page, in the "Proxy Type" section at the bottom make sure the "Use URL Rewrite to inspect incoming requests" is checked and add serveur1 in the Reverse proxy text box. Click Apply to save your changes.

This will create a URL rewrite rule that will redirect all incoming requests to serveur1.

Now we are going to modify this rules and add other rules for the other servers.

Click on your server node again and open "URL Rewrite". There you should see a rule called ARR_server_proxy. This is the basic rule that was created previously.

Select that rule and click edit. Everything on that page should be good to route requests to serveur1 but it's missing the condition to route only the requests coming in for www.domain.com. So add a new condition with the following input values

Condition input: {HTTP_HOST}

Check if input string: Matches the pattern

Pattern: www.domain.com

Now click ok and Apply to save your rule.

This rule will now route every requests for www.domain.com to serveur1.

From there you should go back to the rules page and add new rules identical to this one but with conditions for your other domain names and the other servers.

You can check at the bottom of this page to see all of the HTTP headers and server variables you can use in conditions.

Bonne chance!

ARR is for application routing, what you really want is a proxy server such as ISA Server.

Reverse proxy for 3 internal web servers

neolith13 — Wed, 13 May 2009 19:45:23 GMT

Hi,

Sorry for my bad english (i'm french :))

I try to figured out how to setup this famous ARR for reverse proxy for three internal web servers.

I'd like to have this configuration

Wan (www.domaine.com: 80)--> Reverse proxy (IIS7 with ARR module installed) --> serveur1 :80

Wan (inside.domaine.com:80) --> Reverse proxy (IIS7 with ARR module installed) --> serveur2 :80

Wan (mail.domaine.com:443) --> Reverse proxy (IIS7 with ARR module installed) --> serveur3 :443

Does ARR work for that ? Where can i find all good documentation to realize this configuration ???

I'm totally new on windows 2008 servers and IIS7... used to work with 2003 and IIS 6....

All help will be appreciated !

Thanks !
