Is this possible?
We have setup ARR on our server and added a new binding for SSL and URL Rewrite using the Reverse Proxy rule, and it works fine.
Would it be possible to edit this, so say for example...
Binding Address: server1
https://server1/portal/server2 > Uses ARR to go to http://server2 internally.
https://server1/portal/server3 > Uses ARR to go to http://server3 internally.
What im trying to say, is it possible to have multiple reverse proxy's from one site's binding using URL Rewrite?
Or is it possible to build something like that in PHP?
Yes this should work just fine. The only thing you have to take care off is that you use outbound rewriting to modify the URL's in the content from server2 and server3 to add /portal/server2 and /portal/server3 to any URL's otherwise static content might not load and links to internal pages might not point to the correct URL's.

I have many sites hosted on IIS on same machine. Only for one site, I need to have reverse proxy setup. I have written rewrite rules for this site and forward some request to another site hosted on different machine.
Will enabling proxy on application request routing affect other sites? Will it have an affect the performance of other sites?
Eg: I have following websites(few are wcf services)
localhost/A
localhost/B
localhost/C
localhost/D
Only the website C needs reverse proxy, so I have written rewrite rules for it. How will enabling proxy effect A, B and D sites
Yes you can enable Reverse proxy for one website and ensure that it does not affect the others.
You mentioned that you have 4 websites but in the example, you gave description of "application" and not website. Since its unclear what your architecture looks like, I'll go ahead and give solution to both.
Considering you have a single website and multiple applications within it but you want to enable proxy for just one application, following is what you need to do. Open the URL rewrite section, under pattern, choose regular expression and add ^application_name/(.*) For example, ^c/(.)
But if you have multiple websites and want to reverse proxy just one of them, then open URL Rewrite and add a condition for "HTTP_HOST" and its value. This will ensure that only requests for specific website's hostname will be reverse proxied.
With respect to performance, having URL rewrite on one of the websites will not have any impact on other websites. If you are still unsure and want to play it safe, you can have each website running on separate application pool. That way they have their own w3wp process and are independent of each other.
I essentially have the same issue as desribed here Redirect HTTP to HTTPS in Azure Application Gateway but am trying to solve it a different way.
My back end web application works fine when both http and https are open on the AAG, however when you click on a link generated by the webapp to another page the url sent back to the client is for http not https. Obcviously the proper solution is to make the web app aware it is behind a reverse proxy and generate links accordingly.
In the short term I have been attempting, and failing, to use the IIS url rewrite module to either:
a) Using an inbound rule, rewrite (not redirect) the incoming URLs as https which ought to force the responses to contain https urls (a redirect causes an infitite loop as AAG forwards everything to the back end web servers as http). I'm guessing this is impossible because its essentially creating a secure channel between itself.
b) Using an outbound rule, rewrite the responses so the urls are https instead of http. This is proving to be very difficult as I don't understand what parts of the responses I need to be modifying. I'm hoping this approach is possible though?
For the uninitiated, the answer is to use custom tags in an outbound rule, which match the html elements containing the values that need modifying.
The drawback is of course that it means the web server is having to do a patter match & replace on every single page it serves unless you can use conditions to limit the scope. Still very inefficient compared to fixing the code so it is proxy aware!
I'm trying to achieve wildcard hostname mappings in IIS 8.5. As they don't exist, I'm trying to use URL Rewrite.
I have two formats of URL,
<anything>-foo.mydomain.com
<anything>-bar.mydomain.com
I want to map these to two different sites in IIS, for example
<anything>-foo.mydomain.com --> foo.mydomain.com/<anything>
<anything>-bar.mydomain.com --> bar.mydomain.com/<anything>
I'm trying to configure a URL Rewrite rule at the machine level, but I've got some problem.
If I set it to Redirect it works. If I set it to Rewrite I get an IIS 404.4.
Can anyone shed any light on this?
Here are my settings:
http://cl.ly/a6tK
You can only rewrite the URL to the same site and same application pool. For example:
http://foo.com/bar to http://foo.com/
You need to install Application Request Routing and enable Proxy. Then it will work with URL rewriting to remote servers (regardless where or what they are) since the routing will take care of that.

I have a scenario where I need to two different subdomains to come through the firewall and be rewritten or redirected to areas on the server. For example if I have sub1.mydomain.com/testsub1.html entered externally, I want it to hit the IIS "Default web site/folders/sub1/testsub1.html" and likewise, if sub2.mydomain.com/testsub2.html is received I want it to go to "Default web site/folders/sub2/testsub2.html". We were told that URL Rewritew would be the way to go on this. So we set up rules in the Default web site, to use the MatchURL pattern for:
1. sub1.mydomain.com(.) and to rewrite it to "Default web site/folders/sub1(R:1)" with the action type of Rewrite.
2. sub2.mydomain.com(.) and to rewrite it to "Default web site/folders/sub2(R:1)" with the action type of Rewrite.
If I hit http://sub1.mydomain.com/testsub1.html, I get a file not found error. What I am seeing in the logs is the GET /testsub1.html. If I change the URL to http://sub1.mydomain.com/folders/sub1/testsub1.html, it works perfectly and I see GET /folders/sub1/testsub1.html in the logs and the proper page is displayed in the browser.
What am I missing to make this work without the full path?
Bindings are the best way to handle this. They can listen on the same IP address for different hostnames. Create two separate websites in IIS and configure each of their bindings for that particular subdomain.

I would like to rewrite a subdomain so it is passed as a querystring to a site. Take the following scenario.
IIS Config:
Site A (bindings: *, site-a.com)
Site B (bindings: site-b.com)
Rewrite rules:
"sub1.site-a.com" -- rewrite to -> "site-a.com"
"sub2.site-a.com" -- rewrite to -> "site-a.com"
"sub1.site-b.com" -- rewrite to -> "site-b.com?subdomain=sub1"
"sub2.site-b.com" -- rewrite to -> "site-b.com?subdomain=sub2"
If I make the rewrite rules in the IIS server settings, site-a.com will capture all the rewrites because the original url match the default binding on site-a.com instead of matching the bindings against the rewritten urls. Is there any way around this behavior?
If you were to place a reverse proxy in front, say Apache, this would be possible with mod_rewrite.
I do not think that there is any clear way to do this in IIS as it stands.
You need two IP address or move a part of your redirection logic in the websites.
Second solution may not be acceptable, so get a second IP address. It's justified so you won't have any problem to get it.
The solution was to use the proxy in ARR (Application Request Routing). When you write a rewrite rule with "http://" it will be routed through ARR. Problem solved.
